Review all duration spells for error messages and expiration checks

[grannypron]

1. Make a list of all spells in the game that the characters can / should be able to learn.
2. Check them for errors when executing [SpellDuration] if that hook is specified in the specialAbilities database
3. Remove the [SpellDuration] hook if necessary and add expiration mechanic as per Protection From Evil / Prayer fix - see Error when casting Protection from Evil #102 and Prayer spell never wears off #75

I have also checked the following: Bless, Curse, Detect Magic (Cleric), Protection from Evil (Cleric), Protection from Good(Cleric), Resist Cold, Resist Fire, Hold Person, and Find Traps.

Cause Blindness & Bestow Curse are permanent (until dispelled).
