(svn r4826) -Fix: [autoreplace] fixed possible problem when autoreplacing and was number of vehicles (of a type, not total) was reached 

now the new vehicle gets the same number as the old one, completely removing the problem where we could run out of numbers
	since we don't have to find free numbers for the new vehicles, autoreplace should be somewhat faster, specially in late games
	NOTE: in CmdBuildRailVehicle(), bit 0 and 1 in p2 have been switched to make the meaning of bit 0 consistent with the other build commands. CmdCloneVehicle() is modified to follow this as well
