(svn r2262) - Fix: Assertion when vehicle in a depot wants to do pathfinding.

	GetVehicleTrackdir now tries to get a valid trackdir as much as possibly, by assuming that a vehicle is facing outwards in a depot or road station, for example.
- Codechange: [Multistop] Multistop now also tries to find a slot for road vehicles that are in stations, since the pathfinder now properly handles that.
