(svn r12197) -Fix [FS#1788](r12134): show correct last year profit when the train had negative income
-Codechange: use GetDisplayProfitThisYear() to convert vehicle profit to readable form

(svn r12134) -Change: count the number of ticks a vehicle was running this day to calculate running cost
-Fix [FS#1739]: vehicle profit is now counted with 8bit fract, so it is now shown properly in the vehicle details window

(svn r12066) -Codechange: Rename GetBridge for the more common GetBridgeSpec
-Codechange: Remove direct access to the _bridge table in favor of the above mentioned GetBridgeSpec
-Codechange: Rationalize the use of Bridge type pointer

(svn r11916) -Codechange: use enums from VehicleViewWindowWidgets instead of constants
-Fix: refit button widget was not correctly updated

(svn r11910) -Fix: play 'ding-ding' crossing sound in more cases (except gameload and crossing construction)
-Fix: crossing sound is bound to tile, not to vehicle

(svn r11900) -Fix: set correctly crossing state after train reversal, train leaving crossing, train crash
Fixes several ways to leave crossing red forever or to leave it unbarred when there is a train on crossing

(svn r11877) -Fix: another way to crash competitors' train in a station
-Codechange: increase the speed train is approaching line end/semaphore in non-diagonal direction a bit

(svn r11870) -Fix: slow down train when approaching tile we can't enter in more cases
(tunnel/bridge/depot from wrong direction, competitor's track, wrong railtype)
-Fix: do not make crossing red when we can't enter it in any case

(svn r11822) -Codechange: Replaced fixed size custom name array. Names are now attached to their object directly and there is
no limit to the amount of names.
-Fix: NewGRF engines could not be renamed.

(svn r11802) -Fix [FS#716]: do not crash trains when leaving depot to a very long track
-Codechange: use dedicated pathfinder for signal updating, resulting in better performance and possible future improvements

(svn r11760) -Codechange: unify the way how other end of a tunnel/bridge is determined at some places
-Fix: adding road/tram to tram/road bridge was cheaper by one tile

(svn r11731) -Fix [FS#1582]: Clear sprite override data before performing NewGRF wagon attach callback. This stopped
the callback working for autoreplace and when moving wagons from train to train in a depot.
-Fix (r11724): Don't check wagon attach callback for the chain when moving a single wagon.

(svn r11523) -Codechange: Move the CHANCE macros to core/random_func.cpp cause they depend on Random()
-Codechange: Convert the CHANCE macros to functions and rename them fitting to the naming style

(svn r11332) -Fix: vehicles getting a value of 0 on construction.
-Fix: assertion when selling vehicles.

(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.
