Implemented monster spell miscasts. Spell miscasting is now handled

by the MiscastEffect class, which has helper methods to make most of
the non-helper code agnostic with respect to whether the miscaster is
the player or a monster.  Mummy death curses now affect monsters, and
Zot traps now directly affect friendly and good-neutral monsters.
In wizard mode you can force the player or a monster to miscast by
targeting it and pressing 'M'.

Todo/issues/notes:

* Clouds now have a killer_type in addition to a kill_category.

* There aren't any divination monster miscast effects yet.

* Many of the harmless message-only miscast effects are missing
  monster messages.

* If a monster actually miscasts a spell (not getting a mummy
  death curse or setting off a Zot trap) and this kills both the
  monster and the player then the wrong monster will be listed in
  hiscore entry.  Since monsters can't do true spell miscasts yet, this
  can wait.

* There was old, non-functioning code making Zot traps heal, haste or
  turn invisible hostile monsters that triggered it.  I fixed it and
  then commented it out.
