New (rakshasa) unique: Mara, Lord of Ilusions.

This re-uses several ideas from the Emerald Eye FR, and implements the
spell "Mislead": this grants the "Misled" status effect to the player,
and causes on-level monsters to appear (glyph, name and tile) to be
other monsters. Only their appearance is changed.

Healing potions and rain remove this status effect.

Mara also has a beefed-up version of the Rakshasa clone spell: it
instead creates an "exact" clone (slightly altered spells list, and
non-unique status for his clones). Only two will ever be created at
once.

Finally, he has the spell "Summon Player Ghost". This spell creates a
ghost of the player (though marked as a summon, meaning that it
(shouldn't) register a milestone, though it will be treated as a
self-ghost kill) that is hostile. Only one of these should be existant
at any one point in time.

I'm pretty sure that I haven't broken anything, but would definitely
appreciate someone sanity-checking this commit.

Known minor issue: Kirke's summon ugly things being cast while having
the Misled status causes them to show up with no glyph.
