First attempt at pathfinding using boost::graph
little improvement
AITravel now works correctly on exterior cells. As long as NPC don't try to leave cell, it's ok.
Somehow manages to get from one cell to another, but this looks wrong... And I don't know how morrowind do it, because aitravel is completly buggy
check if the NPC is close from a non loaded cell. If yes, AITravel is simply ended.
