added possibility to limit number of edges of city with allowed connections
changed number of parallel track
changed number of connection points to be defined per side

This however requires that we run the fix script after setting paths.

Now we first fix empty cells with incoming connections
then we fix cells with rails and wrong transition maps.

fixed how a-start works. we can now force it to ignore illegal rail elements. This might be a bit dangerous as you need to fix them later one ( done in current code). Maybe better suggestions here!?
