Changed interrupted butchering behaviour as per Johanna's

suggestions/observations:

1) Get rid of option swap_when_safe and its behaviour.

2) If auto-swap butchery is interrupted by teleportation or chagning levels
   (banishment) then auto-swap back if there's no monsters nearby.

2b) Do the same if butchery is interrupted and then later a large position
    change happens.

3) If auto-swap butchery is interrupted by something like poison damage,
   if the butchery is resumed and finished then swap back.

4) If auto-swap butchery is interrupted by a monster, then if the
   new option prompt_for_swap is set the game will ask if you wish to
   swap back from your butchering tool.

4b) Do the same if butchery is interrupted and then later a large
    position change lands you near some hostile monsters.
