(svn r2423) - CodeChange: Include first_engine in the train cache, instead of calculating it all over the place.
- Fix: Also recalculate the train cache values for 'wagon chains' (in the depot without an engine), to avoid possible desyncs later.
- Fix: Make CmdMoveRailVehicle update the caches of the correct trains in all cases.
