changed behavior of fix transition. If only one inbound connection is found to empty cell, let cell be empty and instead fix the incoming line to a dead end in seperate step

removed possibility of more than two connection direction to and from the cities. In this manner we procude nicer and more realistic city infrastructures

added city boarder to as forbidden zone for inner city connection. This strictly seperates inner from outer connections. should help us to get nicer infrastructures.

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!?
