(svn r3422) - Fix: If an engine reaches the rear of a depot, make the engine turn around before it reaches the tile end (same as a normal end of line.) This fixes a bug whereby the engine could poke into the depot and crash with another engine just leaving it.

(svn r3421) - Revert r3412 as it didn't work.
- Fix station builder issue by checking the tile is in bounds.

(svn r3420) - Fix typo made back in r2997...

(svn r3419) - Fix: [FS#40] (Possible) game crash on removing track/road under bridge. This was caused by a wrong tile-occupancy testing where it was assumed that a vehicle's height is only a multitude of 8 (a single height-difference). This is incorrect as a vehicle on a slope will assume all height levels between the lower-and upper-bounds. The crash is still possible as seen in the Flyspray bugreport but this has a different cause.

(svn r3418) - Fix: When removing a town-owned tunnel the player's rating was not reduced, as it checked the ownership of the tunnel after clearing it. Now we perform the rating adjustment before clearing the tiles. (spotted by glx)

(svn r3417) - Make company league table window pinnable.

(svn r3416) - Fix: Disallow building an oil rig above sea level.

(svn r3415) - Fix: Disable the clone and refit buttons in the train view when viewing another player's vehicles, or as a spectator. (thanks to UnderBuilder for pointing this out)

(svn r3414) - Fix: Disable the Fund New Industry menu item and window when connected to a server as a spectator.

(svn r3413) - Fix: Under certain conditions placing a road tile parallel under a bridge would, instead of failing, succeed and place a perpendicular piece.
