(svn r1880) [Codechange] Added isocodes to langfiles and support code to strgen (Lauri Nurmi)

(svn r1879) Revise name handling, no functional changes

(svn r1878) - Change: MSVC.NET project file, remove WITH_SDL since it is really unneeded from windows builds. And put back 'treat warnings as errors' flag.

(svn r1877) Forgot to remove two now unused variables

(svn r1876) Make placement of oil rigs and refineries map size agnostic

(svn r1875) Effect vehicle overhaul: enumerate sprites, descriptive names for functions and miscellaneous improvements

(svn r1874) Fix bug introduced in r1839 which placed snow covered trees below the snow line ([1121680])

(svn r1873) Ignore SIGPIPE

(svn r1872) -Fix: Fixed an inline problem which caused MSVC6 to not compile :/

(svn r1871) Daily langfile updates #2.

(svn r1870) Added new language: lithuanian

(svn r1869) Fix some bugs in the bulldozer movement implementation.
Now they move in a sane pattern.

(svn r1868) Improve readability of the bulldozer movement code

(svn r1867) Include tables/sprites.h only in files which need it

(svn r1866) -Fix: Intercepted generated maps with 0 towns on it. Currently just an
error() is called, some more graceful handling should be implemented
later.

(svn r1865) Fix some warnings

(svn r1864) Automatic langfile updates

(svn r1863) Give the effect vehicle type enums more descriptive names and use the enum as parameter type for CreateEffectVehicle*()
-Fix: [1116619] Generate the correct smoke type for diesel trains

(svn r1862) - Settings: No longer treat warnings as errors for VS.Net project files...just until spritecache is fixed up :)

(svn r1861) Constify Get(Non)Sprite()

(svn r1860) The sprite header endianness issue was solved in r1855

(svn r1859) Miscellaneous style changes

(svn r1858) Let ReadSprite() handle the subtleties of loading a sprite, not its caller

(svn r1857) Rewrite parts of the sprite heap. It's functionally equivalent but should be easier to read and maintain.

(svn r1856) Make GfxInitSpriteMem() static, because it's only used withing spritecache.c

(svn r1855) Handle endianness of sprite headers when loading a sprite, not everytime when accessing it

(svn r1854) Split GetSpritePtr() into GetSprite() for regular sprites (returning a Sprite*) and GetNonSprite() for "sprites" of type 0xFF (returning byte*)

(svn r1853) Move spritecache function declarations into a header of their own and use SpriteID as parameter type where appropriate

(svn r1852) Start cleaning up sprite handling:
- Complement the sprite header struct with a variable sized array for the sprite data and rename it to Sprite.
- Use the correct type Sprite* instead of casting all the time (this causes some "assignment from incompatible pointer type" warnings, nothing serious, will be resolved soon)

(svn r1851) - Language: added Frisian translation (no strings have been translated yet)

(svn r1850) Change the last consumers of str_buffr so they use local static buffers now and remove the global array str_buffr.

(svn r1849) Use the cheat entry enum for CheatEntry.type and remove unused enum values

(svn r1848) Remove the obscure feature of initialising the edit box with the contents of str_buffr - it was unused anyway.
Remove it from the chat box too, which inherited it via copy&paste.

(svn r1847) Adjustment for MorphOS to unbreak the build there and removal of some now obsolete preprocessor magic

(svn r1846) - Fix: VS6 project file (bociusz)
- Fix: VS6 fkcing borkdness should be abolished

(svn r1845) - Revert r1835 since it totally screws network compiling
- Fix: fix some VS.NET warnings
- Add missing file to VS.NET project file

(svn r1844) -Fix: small protection in oldloader.c, and put the savegame on pause by default

(svn r1843) - Codechange: [NPF] Removed some unused code.

(svn r1842) Fix another typo made in r1834

(svn r1841) -Fix: [ 1117538 ] non-stop orders are no longer accidently skipped

(svn r1840) Repel str_buffr and use local buffers where possible

(svn r1839) Move GetTileSlope() and GetTileZ() into tile.[ch] and use more explicit types as parameters

(svn r1838) Ship depots are on water, not roads

(svn r1837) GetTileOwner returns Owner, not bool
Also assert() that the TileIndex is valid

(svn r1836) Clean up some strange constructs concerning socket options

(svn r1835) Reduce the visibility of network_core.h

(svn r1834) - Fix: NPF does not check the owner of its target, busses try to enter other players' depots. TODO
- Add: asserts to find the v->u.rail.track == 0 problem.
- Add: IsValidDepot(), IsValidTown(), IsValidSign(), IsValidVehicle(), IsValidStation()
- Add: GetTileOwner(), IsTileOwner()
- Codechange: Replaced IsShipDepotTile(), IsTrainDepotTile(), IsRoadDepotTile() by IsTileDepotType().
- Codechange: typedeffed the MAP_OWNERS as Owner. Should be used as variable type.
- Codechange: Replaced a few uint by TileIndex.

(svn r1833) byte -> char transition: the rest

(svn r1832) Next byte -> char iteration: custom names

(svn r1831) -Fix: Scenario Editor now handles human-made roads better (try to build
a city layout before placing the city, finally that works very nice)

(svn r1830) -Codechange: small stuff to make the file more beautiful (tnx Tron)

(svn r1829) -Fix: fixed some compiler warnings (tnx to Tron for the Makefile-flag)

(svn r1828) New warning flag especially for truelight (:<

(svn r1827) Next iteration of the byte -> char transition: some string drawing functions and buffers

(svn r1826) -Feature: a brand new OldLoader so OpenTTD is TTD(Patch) compatible
again.. kind of anyway. Still needs work for the extra chunks
TTDPatch provides, and which we use too, but not in the same way..
- Also, no longer BE is a problem, reading is BE/LE safe.
- Tnx to Bjarni for the BE testing, Tron for the help on the BE,
Darkvater for helping out, and Mek for providing me with the correct
information regarding TTDPatch savegames

(svn r1825) Further style improvements:
- uint16 -> StringID where appropriate
- if cascades -> switch
- remove redundant ifs
- misc. stuff

(svn r1824) -Codechange: made ChangeIndustryProduction a bit more readable

(svn r1823) Get rid of some ugly cast magic concerning language packs

(svn r1822) Const correctness

(svn r1821) Move generic string handling functions to string.[ch] and introduce stre{cpy,cat}, see string.h for their semantics
