Subject: Allow vaults to override monster spells with spells:<xyz>

Vaults can now override monster spell sets, or give non-casting monsters
spells, and mark monsters as wizard or priest types.

The M_ACTUAL_SPELLS, M_SPELLCASTER and M_PRIEST monster class flags are
converted into MF_* flags at monster creation/polymorph time, and only the
per-monster flags are checked when determining wizard/priestliness. See caveats
in level_design.txt.
