Add some chaos attacks/weapons. Missiles and launchers of chaos fire a bolt of

a random type (including enchantments, which isn't so good since they don't
have a visible beam).  Might want to add BEAM_CHAOS and make it a beam of that.

Weapons of chaos either does a random brand effect (fire, poison, etc) or a
random chaos effect (which includes cloning the attack victim).

The AF_CHAOS monster attack flavour either does a random monster flavour or
chaos effect (same chaos effects as for weapons).

The relative frequency of all the different effects/brands/flavours no doubt
needs adjustment.

All of this is currently only available via Xom.  10% of all common-type demons
sent in by Xom will be chaos spawn (the only kind that use AF_CHAOS, and never
randomly generated otherwise).  All item gifts from Xom which are generated
with a brand will have their brand switched to chaos (this should probably be
made to happen less than 100% of the time).  And finally one of Xom's bad acts
is to upgrade a non-branded weapon of a nearby hostile monster to a chaos brand
(this might need to be made less (or more) common).

Oh, and if a randart has a brand which would be identified if it were merely an
ego weapon, it now identifies the RAP_BRAND property of the randart.
