(svn r13531) [NoAI] -Add [API CHANGE]: when building a bridge/tunnel for road/tram, the BuildBridge/BuildTunnel function will now also make two half-road/half-tram pieces on both ends of the bridge/tunnel, so it is easier for you to connect them to your network. This give a more consistant behavior for road.
-Note: if the road pieces failed to build, but building the bridge/tunnel succeeded, the function still returns true (for the obvious reasons)

(svn r13530) [NoAI] -Fix (r13528): regression.txt was wrong

(svn r13529) [NoAI] -Fix: don't suggest something is DiagDirection if it in fact isn't

(svn r13528) [NoAI] -Change: regression so it doesn't lose money as fast as it did.

(svn r13527) [NoAI] -Fix (r13525): squirrel_export doesn't like extra semicolon

(svn r13526) [NoAI] -Fix: some namespace problems and forgotten pre-condition

(svn r13525) [NoAI] -Add: added AIEventEngineAvailable and AIEventStationFirstVehicle

(svn r13524) -Codechange: use the typesafe QSort for vehicle sortings
-Prepare: vehicles sorting for convsersion to GUIList

(svn r13523) -Codechange: replace qsort by the internal typesafe QSortT for resolution sorting

(svn r13522) -Codechange: Replace the qsort of the highscore with one of the internal sorters

(svn r13521) -Codechange: Use GUIList sorting instead of poll & sort for CompanyLeagueWindow

(svn r13520) -Fix (r13375): pointer has to be valid before it can be loaded to (SLE_STR)

(svn r13519) -Feature[newGRF]: Implement var 63, variational action2 variable for Houses.
Or, in more simple terms, the check for the animation frame of nearby house.

(svn r13518) -Fix [FS#2083]: Properly count number of non-north housetiles.

(svn r13517) -Add: remaining used typesafe versions of the mem* functions from <string.h>

(svn r13516) -Codechange: Move MemCpyT to a fitting core header
-Codechange: Split the sorting code from the sortlist to an appropriate header

(svn r13515) -Codechange: Widget enumification for scenario editor

(svn r13514) -Codechange: Removal of dead code (or useless, to be more exact)

(svn r13513) -Codechange: Give proper message when building a river fails.
Give proper description of a river tile with the Query Tool.
Extracted (in part) from FS#1884, by Ammler

(svn r13512) [NoAI] -Fix: don't load a library over and over, but keep track of which libraries we have loaded (per AI) and re-use it where possible (reduces memory-footprint)
[NoAI] -Fix: change the fake-library-name-counter to a per AI value, not global
[NoAI] -Fix: Load the script inside the thread, not in the main thread. This avoids unneeded error-handling

(svn r13511) [NoAI] -Fix: add a reference to objects given in Valuate(), so they remain valid during their usage. This allows nameless functions (lambda functions) in Valuate() on long lists.

(svn r13510) [NoAI] -Fix: be a tiny bit more strict for AIAbstract.Valuate() (check the type of the first 2 params)

(svn r13509) [NoAI] -Sync: with trunk r13472:13508.

(svn r13508) -Fix (r7733): incorrect usage of strtoul

(svn r13507) -Fix (r12856): first engine change should've been moved too

(svn r13506) [NoAI] -Change [API CHANGE]: like AIVehicle, AIStation, .. restrict AISign to only your own signs
[NoAI] -Remove [API CHANGE]: the change above makes AISign::GetOwner() obsolete, and is therefor removed

(svn r13505) -Fix: clear the memory for the new AI during the loading of a savegame so it does not try to execute commands generated in a different savegame, which could be resulting in the AI trying to give orders to stations that do not exist.

(svn r13504) -Codechange: enumify some widgets for scenario editor. More work is required.

(svn r13503) -Fix(r13173)[FS#2073]: Wrong widget numbers & event handlers were assigned to the zoom in and out buttons in the scenario editor

(svn r13502) -Fix (r11212): drawing of zoomed out partial sprites could cause deadlocks or crashes

(svn r13501) -Feature(tte): ctrl+click on sign you own to remove it (Osai, planetmaker)

(svn r13500) [NoAI] -Fix r13497: minor glitch in slope-check (Yexo)

(svn r13499) -Codechange: Allow drawing (ugly) leveled foundations on steep slopes, just in case someone needs them for fallback.

(svn r13498) [NoAI] -Add: added 'pathfinder.road' to the regression

(svn r13497) [NoAI] -Add [Library]: pathfinder.road, a basic road pathfinder (no bridges/tunnels (yet)) (patch by Yexo, very nice job!)

(svn r13496) [NoAI] -Fix: if a library depends on an other library, the import became globally known, which defeats the idea of imports. They are now restricted to their scope, and 'import' returns the class of import (if any)

(svn r13495) -Fix: scrolling the main map with the keys speed was influenced by movement of the mouse.

(svn r13494) -Fix: a little documentation + copy-paste mistake for sprite.h.

(svn r13493) [NoAI] -Fix: ReloadAI should reload the AI correctly, no matter what you named your dir

(svn r13492) [NoAI] -Add: added the 'standard' functions max() and min() in global scope

(svn r13490) -Add: a seperate icon for aqueducts

(svn r13489) -Fix: first determine where to *exactly* build a house before asking a NewGRF whether the location is good instead of possibly moving the house a tile after the NewGRF said the location is good.

(svn r13488) -Fix (r13485): track wasn't removed on company bankrupcy when there was a ship on lower halftile

(svn r13487) [NoAI] -Fix: tram bits are not to be considered buildable in any case.

(svn r13486) [NoAI] -Add: function to determine what TransportTypes a tile holds.

(svn r13485) -Fix: let ships also navigate on half-tile sloped watery rail tiles.

(svn r13484) [NoAI] -Fix [API CHANGE]: AITile::IsBuildable() now returns 'true' on coast tiles
[NoAI] -Fix [API CHANGE]: Renamed AITile::IsWater() to AITile::IsWaterTile() to be more consistant; also, it no longer returns 'true' on coast tiles
[NoAI] -Add: added AITile::IsCoastTile(). Building on such tiles is in general more expensive

(svn r13483) [NoAI] -Fix: oops... IsBuildable thought trees were not buildable, silly of course (tnx Yexo)

(svn r13482) -Codechange: Use "extended bytes" in Actions 3 and 4 for vehicles

(svn r13481) -Codechange: add 'B' keyboard shortcut to build aqueduct (planetmaker)

(svn r13480) -Fix [FS#2050]: RVs stoppping at drive through stations of other companies.

(svn r13479) -Codechange: don't use word 'bridge' for aqueducts that often

(svn r13478) -Codechange: don't use GetBridgeSpec() for aqueducts

(svn r13477) -Fix (r13464): correct tile type in the Query tile info window

(svn r13476) -Fix: draw canal borders for locks and when directly next to a aquaduct entrace but under the aqueduct.

(svn r13475) -Fix (r13464): crash on destroying aquaduct with ship on in and on company bankrupt

(svn r13474) [NoAI] -Fix: remove the restriction of 10 params per Valuator

(svn r13473) [NoAI] -Sync: with r13417:13472.

(svn r13472) -Backport (r13467 from NoAI): make CmdRemoveRoadStop use p2 as documented (only look at bit 0, not at the complete value)

(svn r13470) [NoAI] -Change [Library CHANGE]: allow in graph.aystar to give a custom param to the callbacks, so you can send in an instance of yourself

(svn r13469) -Codechange: add support for loading Action 0x05, type 0F: "tracks for slopes". It's not useful right now, but it will be in the future.

(svn r13468) -Fix: make aqueducts a little more expensive than normal bridges and disable terraforming of aqueduct bridgeheads; one can't terraform normal canal tiles either.

(svn r13467) [NoAI] -Fix [OpenTTD Core]: make CmdRemoveRoadStop use p2 as documented (only look at bit 0, not at the complete value)

(svn r13466) -Fix (r13464): slope checking got lost during development...

(svn r13464) -Codechange: support NewGRF Action 0x05, type 12.

(svn r13463) [NoAI] -Change [Library CHANGE]: AyStar is now more object oriented, and you can indicate the amount of iterations FindPath should do in one go (tnx to Yexo and TrueBrain)

(svn r13462) -Codechange: move DriverFactoryBase destructor definition from header file (saves ~16kB)

(svn r13461) [NoAI] -Fix: add A* to regression, so we test it a bit (very basic test ;))

(svn r13460) [NoAI] -Add [Library]: added graph.aystar, an A* implementation (Yexo)

(svn r13459) [NoAI] -Fix: final fixes in binary_heap

(svn r13458) [NoAI] -Fix r13457: fix the regression Luke...

(svn r13457) [NoAI] -Fix: fix the binary heap implementation to ... remain a valid binary heap tree :)

(svn r13456) -Codechange: use AllocaM() macro instead of alloca() at most places

(svn r13455) [NoAI] -Fix: extend the regression to test the queues a bit more

(svn r13454) [NoAI] -Fix: kill all AIs when leaving game in any way (restart, loadgame, ..) (tnx Yexo for reporting, and glx for fixing)

(svn r13453) [NoAI] -Fix: allow import inside a library (or class, for that matter)

(svn r13452) [NoAI] -Fix: minor coding style. Also, BinaryHeap is based on work by GeekToo!

(svn r13451) [NoAI] -Fix: no comments ...

(svn r13450) [NoAI] -Change [API CHANGE]: renamed library category 'sets' to 'queue', as it represents more what the implementations do

(svn r13449) [NoAI] -Fix: .tar support is not yet available inside the library-structure .. disable it for now

(svn r13448) [NoAI] -Fix: indicate in doxyfile too that this is NoAI

(svn r13447) [NoAI] -Add [Library]: Binary Heap ( O(ln n) insert/pop )
[NoAI] -Fix [Library]: Priority Queue now is a bit more robust (and hit version 2)

(svn r13446) -Fix(r13443): changed the var previously introduced from 69 to 46, as no param was required (thanks frosch)

(svn r13445) -Codechange: make 32bpp_optimized blitter ~10-20% faster in drawing (depends on architecture and compiler)

(svn r13444) -Codechange: make the order GUI somewhat more efficient. The most used options can be done with a single click now.

(svn r13443) -Feature[newGRF]: Add var 0x69 for industries, long format construction date.
Same as var B0, but base year is now 0, instead of 1920

(svn r13442) [NoAI] -Add: added 'rescan_ai' console command. Use it to rescan the ai dir when you add AIs or libraries without needing to exit and restart openttd.

(svn r13441) [NoAI] -Fix (r13440): NO_THREADS compilation

(svn r13440) [NoAI] -Add: introducing ai/library, a method to load libraries into your AI.
-Note: to use a library, use in your AI: import("categorie.name", "LocalName", version_number_of_library)
-Example: import("sets.priority_queue", "PQ", 1); local pq = PQ(2); pq.insert(2, 1);
[NoAI] -Add [Library]: sets.priority_queue (based on work by Morloth)

(svn r13439) [NoAI] -Fix: set svn props and keywords, and fix Author and Version

(svn r13438) [NoAI] -Fix: sq_pop when needed, to make sure the stack keeps as clean as possible

(svn r13437) -Feature[newGRF]: Add long format introduction and maximum construction year for house.

(svn r13436) [NoAI] -Change: call the constructor of the SQ when the ->Start() is called of AIController. This makes sure the SQ code is always executed inside the thread, and not inside the main-thread. This has no change what so ever for AIs.

(svn r13435) [NoAI] -Fix r13432: still the statements were wrong ... 3rd time is the charm :)

(svn r13434) -Fix (r13317): news window with invalid news item could be shown

(svn r13433) -Codechange: remove a now useless global variable.
-Fix: MP advertising was not advertising.

(svn r13432) [NoAI] -Fix r13290: in case of a network-client, AI_StartNewAI() should never be called

(svn r13431) [NoAI] -Fix: AIs in multiplayer is no longer an experimental thing
[NoAI] -Fix: start_ai now reports nicer errors when it fails

(svn r13430) [NoAI] -Add: added AIEventIndustry(Open|CLose)

(svn r13429) [NoAI] -Fix: don't mix eol-style when updating files (squirrel_export)

(svn r13428) [NoAI] -Fix r13427: if you do something, do it right (RandRangeItem of course has the same 'problem')

(svn r13427) [NoAI] -Fix: RandRange(max) of course can never return max, but the highest value is max - 1 (tnx Yexo)

(svn r13426) [NoAI] -Fix: in the unlikely case an AI is killed before his ->Start() was started, an assert was triggered

(svn r13425) [NoAI] -Fix (r13355): obiwan in AIDebug window

(svn r13424) [NoAI] -Codechange: strdup strings returned by Squirrel when it's called from openttd.

(svn r13423) [NoAI] -Remove: old code telling we no longer support AIs without 'info.nut'. We hope everyone did that by now :)

(svn r13422) [NoAI] -Change [API CHANGE]: remove Stop() as part of the AIController. This means you no longer need to have a Stop() function in your AI, nor is it ever called. This because it was silly, never used, and couldn't do anything real (all Sleep/DoCommands resulted in an assert, as the game expected the company to be gone).

(svn r13421) [NoAI] -Fix: remove the need for a Sleep(1) before executing a command at the beginning of Start(), by skipping the first tick before calling Start() in the first place

(svn r13420) [NoAI] -Add: function to get the town rating.

(svn r13419) -Fix [FS#2063]: Entries in the bridge list were not sorted when the window was just opened.

(svn r13418) [NoAI] -Sync: with trunk r13380:13417.

(svn r13417) -Fix (r12945, r13413): freeing the ThreadObjects in a manner that hopefully doesn't cause crashes.

(svn r13416) [NoAI] -Fix: make doxygen happy again

(svn r13415) [NoAI] -Add: added AITileList_StationType, giving all the tiles on which a station of your requested type is, for a given station

(svn r13414) [NoAI] -Add: added AIStation::HasStationType(station_id, station_type) to check if a given station has a given station-type

(svn r13413) -Codechange: remove some enums that haven't been used for years.

(svn r13412) -Add: OTTDThreadTerminateFunc, for all thread systems, which is called when a thread is terminated. Now GenWorld- and SaveLoad-thread cleanup theirselves correctly, while Fibers don't (as that causes access-violations)

(svn r13411) -Codechange: remove the return value from the thread procs because it is never used.

(svn r13410) [NoAI] -Add: functions to perform town actions (advertising, bribing, building statues, etc).

(svn r13409) -Fix: division by zero when one would press 'd' (skip order) when there's no order.
