Fiddle with a variety of monster attack type messages

Alembics and blazehearts both punching were using attack types not actually
in active use previously, as were dream sheep headbutting foes. In this
same spirit of being a little more specific with reasonably straightforward
attack types, the following not-weapon-using enemies now use attack types
and words other than "hit":

* iron golems punch both times,
* draconian monks punch for their first hit (and still kick + tailslap
  after),
* ushabti headbutt (they're too rigid to do much else),
* spatial maelstroms and thermic dynamos touch and engulf,
* and toenail golems gore.

None of these should affect gameplay- even if one dragged an undying
armoury over to draconian monks, they already preferred their bare fists
before any other weapons.
