(svn r8145) -Featurette: Allow for Tropic Farm to plant fields after producing cargo, like its counterpart in temperate climate.

(svn r8144) -Fix: [FS#163] When a station is removed, vehicles do not get excessive payment any longer, as the origin TILE is now stored as long as the origin STATION for the transported cargos. Basically this is only a temporary fix until cargopackets are implemented, but it fixes one of the oldest known bugs (Special Thanks to Darkvater for lots of testing)

(svn r8143) Remove the landscaping button from the build toolbars.
The landscaping toolbar can be reached at least as easy directly from the main toolbar.
Further two of the four toolbars uses 'l' as keyboard shortcut for this button, which plain does not work (The letter has to be uppercase).
This was covered by the fact there is a global shortcut 'L' to open the landscaping toolbar, so the individual checks in the four build toolbars were redundant anyway.

(svn r8141) -Fix r8128: [OSX] now OSX can compile again.
Note: this is again another not so nice workaround as Objective C fails to include C++ code in the headers
We should move to Objective C++ as soon as possible, but such a change is not done overnight and
this quick fix will allow OSX to compile until the prober solution is done

(svn r8140) -Fix [FS#54]: Combat helicopter flies past factory before it shoots. Chopper comes from the north-east, so it looks in +15 direction (forward), not -15 direction. Probably bad copy-paste from airplane-destroys-oil-refinery disaster.

(svn r8139) -Cleanup: simplify auto_ptr initialization (Tron)

(svn r8138) -Cleanup: comment style corrections

(svn r8137) -Fix (FS#551, r4259, r4320): roadstop->num_vehicles was wrong for savegames with version 24 or lower and do not calculate roadstop->num_vehicles when reading the roadstops as the vehicles might not be loaded at that moment.

(svn r8136) -Codechange: Station spread rectangle manipulators turned into StationRect::methods.

(svn r8135) -Fix (r7582): Don't assert on duplicate non-static grfs when removing duplicates as the PEBKAC effect can result in the user adding the same grf's in the config file.
