NPC speech library fixes
Changes from original repo

monster.kod Buy() now handles mobs that sell from inventory (Izzio,
Pacal).
Bonk fixes

No more bonking blind/dazzled players to allow them to see under some
circumstances.
Bonk can also be cast by non-DMs, for the rare occasions where a monster
or player will have the ability to cast this.
