changeset 3347:1683eb29f80d draft

(svn r4131) - CodeChange: Add proper semantics for StationID for such variables instead of using the general uint16-type. StationID was added for depots, waypoints and stations where necessary. We probably need to change GetDepot(), IsDepotIndex(), IsStationIndex(), GetWaypoint() and IsWaypointIndex() as well to use StationID.
