Subject: Generalize swapping two pieces of terrain in function swap_terrain().

Encapsulate filling out a corpse object for a particular monster in
fill_out_corpse().

Started work on "swap chaos weapon with weapon of victim" chaos effect, but am
putting that off until there's some actor class virtual methods for changing
inventory and equipment.
