FleeingNpc AI [COMMITED]

Thanks to DnR's implementation of the latest L2j Geoengine i finally was able to  finish my FleeingNpc AI.

Before the Geodata "canMove" check i was using the Fear skill effect on attack.
But that wasnt retail like at all.

It works like a charm now.
They will avoid walls ,and dont get stuck anymore.

Enjoy.
