- Fix: [ 1203769 ] [NPF] NPF tries to plan over bridges, through tunnels, over level crossings of other players. (glx) - Codechange: Renamed TRANSPORT_MAX to TRANSPORT_END and added INVALID_TRANSPORT. - Codechange: Moved IsLevelCrossing() from tile.h to rail.h - Add: GetCrossingTransportType(), which returns the transport type (road, rail) of both tracks on a level crossing. - Removed old TODO that was fulfilled already.
