Idea: crossing tracks in the air

[rubberduck]

my idea is that you can cross two roads in the air to a crossing
the borders of the track-segments must not intersect because this would avoid driving over the crossing.

there is also a difference to a track that goes under an other track, you can get stuck on the edge of the two crossing tracks, that could make it harder.

Hah, yes. So making bridges crossing on same heigh level, which requires getting rid of road wall.
And actually making 1 mesh for crossing
Need to think it over but, not sure how to implement it.
This is again difficult since it needs more code in source/road/Road_Rebuild.cpp (which is aready quite magic/complicated).
