Convert some ints to monster_type.

There's a whole lot of places that pass monster_type as int, often
with varying meanings for the value -1. This moves some of these
to monster_type, introducing MONS_NO_MONSTER and MONS_PLAYER as
new invalid special values.

Also improve on the autoexclude descriptions.
