Pathfinding

[stefanhendriks]

At some point we might need path finding for units, especially when maps become more complex (they are rather flat and easy right now).

A* is a well known algorithm. But perhaps Fringe is also a good alternative.

@arjenvanderende maybe we should do this next? It would be a great improvement. We could even do a small step before full-fledged path finding.
