(svn r2514) - Codechange: [NPF] Move the checking of railtype into a funciton IsCompatibleRail().

Browse Source 
- Codechange: [NPF] Check the railtype along a route against the engine type instead of against the previouse tile. This clears the way for electriefied rails.
- Add: [NPF] [ 1209644 ] A penalty for crossings (peter1138)
