[fix] wegbauer and crossings

[gerw]

This patch will fix a issue with wegbauer and crossings:

If a tile has, e.g., a road, no check for crossings is done. So if you have a straight rail track with roads crossing consecutively, you can build a road directly over the rail track.

This patch forbit to cross other player's rail. Is this intended ?

Foe example, player 1's rail and cityroad is crossing, but other player can't use this crossing.

I will have a look for it tomorrow.

Edit: Try this, evil tester

But on the other hand it is not possible to cross other players rails with roads! So using other players crossing creates a loophole here.

This is intended, as I can also use other player roads.
