Enable pathfinding for patrolling monsters who lost their patrol point.

Fixed patrol definitions in maps not actually working.

Tested both by teleporting the minotaur in a labyrinth. About 50 turns
later it arrived back in its lair. :)

Since the minotaur proved to have a high magic resistance, it had plenty
of time to loot the stash at the labyrinth entrance once I'd woken it 
before I finally managed to teleport it away (in wizmode you can force 
monsters not noticing you).

This resulted in 
  "A minotaur, wielding the demon trident "Suyn Oma", and wearing a heavily
   runed ring mail."   o_O

It had also picked up a scroll and a wand. Ouch... (but cool!)
