More progress on making pacified monsters leave the level. They'll now

find the nearest exit, and disappear once they reach it.  There's a new 
travel target, MTRAV_EXIT.

Notes:

This is currently very simplistic.  The monsters still don't use 
pathfinding, so if they're blocked, they'll just stand there again.

With shaft traps, the monsters shouldn't try to go directly to the 
target, since they can't disappear at the same time they fall through to 
another level.

With teleport traps, they should only go to them when all paths to exits 
are blocked, and they shouldn't disappear when they hit them.  There may 
also be issues if a monster hits one and reappears nearby, since it 
won't be far enough outside the player's LOS to disappear.
