(svn r11374) -Codechange: Give meaning to the magical number that specifies the color of the text in a DrawString call.
Patch heavily based on BiBB's work (FS#1383)

(svn r11011) -Fix [FS#1129]: GetFirstVehicleInChain did change the game state while being marked const.
-Codechange: do not brute force determine the first vehicle in the chain or previous vehicle, but do it by properly accounting the previous and first pointers when updating the next pointer. This gives a performance increase of about 15% when there are a lot of vehicles in the game.

(svn r8685) -Feature: selecting "end of orders" and clicking delete will delete all the vehicle's orders
If the orders are shared, then it will still unshare the orders like before.

(svn r8397) -Codechange: [orders window] don't move the refit button to the same location as the unload button
instead assert if the widget array place them at different locations

(svn r8293) -Codechange: overloaded ShowVehicleListWindow() so it can open all types of vehicle lists (depending on arguments)
- Also removed some unneeded arguments
- this also allows removing an if-else cascade in ShowVehicleListWindowLocal()

(svn r8128) -Codechange: Split sprite and palette remap into separate 32 bit values.
This lets us increase the sprite width from 14 to up to 29 bits,
effectively nulling the old sprite limit. Table changes in next commit.
