(svn r3157) - Feature: Added patch option to link the terraform toolbar to the rail, road, water and airport toolbars. If enabled, the terraform toolbar will open and close with those toolbars.

(svn r3156) -Fix: removed some cases where autoreplace windows were redrawn when nothing was changed
due to the FOR_ALL_VEHICLES(), redrawing those windows are slow

(svn r3155) -Feature: [autoreplace] autoreplace can now remove cars from too long trains
-Trains will now remember the length of stations it visits and sell cars
when being autoreplaced if they became too long
-If it needs to remove cars, then it starts from the front and sells
all it can find until the train is short enough
-This only works for trains, that knows the station length of the route
so a full uninterrupted run is needed
-a train needs 1-2 runs to detect if the shortest station is expanded
-This feature can be turned on and off in the train replace window
and each company can have it's own setting
-NOTE: minor savegame version bump
