(svn r3101) -Codechange: added _new_vehicle_id
	this var works like _new_train_id and the rest of that kind of vars, except it is set each time a vehicle is build, nomatter what type
	this is a nice tool to code vehicle independent code, which in turn can reduce code duplication
	Right now it's used in ReplaceVehicle() and CmdCloneVehicle()
