(svn r4902) Newgrf : Introduction of the newgrf_cargo files.
Clearing engine and newgrf_engine from cargo related structures.
Apart from moving stuff cargo related, there is nothing really newcargo for now.

(svn r4493) Newgrf : Action 04. Beginning of implementation.
Some TODOs left, but the core is there.
Thanks to Peter1138 for code, advice and patience
And to Patchman for letting us define a lot of langids :)

(svn r3472) - [PBS] Remove from trunk. Anyone interested can still find it in branch/pbs. This reverts revisions r3158, r3140, r3075, r2977, r2674, r2625, r2621, r2529, r2528, r2525, r2524, r2519, r2517, r2516, r2507, r2499. (in conjunction with Tron)
- The only change is that the nsignalsw.grf file is kept and that existing nightlies with PBS signals get those signals converted to combo-signals.

(svn r2909) Game would hang where the autosave_on_exit was activated.
- Updated VS.NET and VS6 project files changed AI files

(svn r2866) Move all functions and tables which aren't directly involved in managing the sprite heap to a new file gfxinit.c.
This doesn't ease the global variable mess, but makes the distinction between sprite heap and gfx loading routines easier.

(svn r2810) Threads may now return information when they terminate using a void*.
Also add the new files to the MSVC project files.

(svn r2606) -Codechange: renamed ai.c to ai_old.c, and ai.h to ai_new.h to make room
for a global AI-handler

(svn r2454) * Codechange: Move #include "stdafx.h" and "openttd.h" from rail.h to rail.c
* Codechange: Move declaration of lookup arrays into the functions that need them. This doesn't pollute the global namespace with the array names.
* Add: rail.h to the openttd.vcproj and openttd.dsp for MSVC.
