Add Brain enum with hunting foxes; move the A* into the sim

Browse Source

NPC strategy is now a Brain field on the entity (Idle, Wander, Hunt(Prey))
that Sim::think matches on, so behavior is data independent of species.
Hunt follows the first step of an A* route to the nearest prey in sight,
replanned every window; the pathfinder moves from game/ to sim/ for that.
A greedy step-toward-target was tried first and oscillated at walls. Bumps
between the same species no longer fight, and six foxes join the hens.
