(svn r13251) -Codechange: rename _patches to _settings as that is more logic.
-Codechange: move all Settings into substructs of _settings in a way that they are logically grouped.

(svn r12913) -Add: ability to backup and restore a player's economic data and data for a vehicle (or chain of vehicles)
Autoreplace uses this with the following benefits:
-Mass autoreplace (the button in the depot window) will now estimate costs correctly
-Autoreplace now either replaces correctly or manages to keep the original vehicle (no more broken trains)
Thanks to Ammler for testing this

(svn r12792) -Codechange: [autoreplace] added a function to figure out if a replacement is needed and if so, to which EngineID
It's designed to save a bit of CPU time, specially if the replacement isn't buildable (think autorenew of old vehicle)

(svn r12791) -Codechange: [autoreplace] Added a flag parameter (listens for DC_EXEC and DC_QUERY_COST) and included more info when returning CommandCost
This allowed cleaning up the code in MaybeReplaceVehicle()

(svn r12648) -Feature: allow four different non-stop types in a single game instead of two. The "TTDP compatible order" setting now only sets the default behaviour of new trains.
-Feature: allow three different load type in a single game instead of two. One can choose full load all and full load any instead of full load being governed by the "full load any" patch setting.

(svn r12629) -Codechange: Split VehicleNeedsService() into Vehicle::NeedsServicing() and Vehicle::NeedsAutomaticServicing().
-Fix (r11052): Disable servicing by service-interval if a vehicle has depot orders.

(svn r12421) -Feature: [autoreplace] the autoreplace button in train depots will now also replace wagons even if they aren't connected to a locomotive
fixed estimated cost in CmdDepotMassAutoReplace() (will still not estimate wagon removal profits)
Made it possible to command CmdDepotMassAutoReplace() to either replace everything or nothing (the button will still happily replace just some of the vehicles if cash premits)

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

(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
