I rewrote the checks that are done when deciding whether a crossing is valid or can be built. The current trunk version has several problems with crossings:
1) One can build tram tracks on road/river-crossings (which exists in pak128), leading to a fatal-error.
2) If one deletes all the ways around the crossing, one can connect to the crossing from the wrong directions.
3) If one deletes the roads to a road/river crossing, one can built canals through the crossing from all sides.
Please test whether there is some unexpected behavior. Also with respect to different players.
This patch is very bad, this remove all things that gerw fixed.

Thank you for testing. I updated the patch.
Seems to be resolved. Thank you.
