When a gas cloud that deals damage is created, it uses
a poison cloud glyph instead of the cloud glyph.
(A bright green '#', or a bright-green recolor of the
cloud tile)
The plane of fire has random "stinking clouds", or
fumaroles, centered on lava pools.
Also make poison cloud glyph override lava, pool and
moat glyphs.

It's not great, but the best I can do without her looking like some
sort of Zombie (most of the tiles try to follow rules - dark-green=zombie,
green=gnome, blue=dwarf, etc. in order that the player can recognize the
patterns, rather than concentrating too much on the details).
