Spells: NPCs using inappropriate spells.

[nilbog]

There is an ongoing project that should be completed by velious release - npcs will only cast spells appropriate for their era.

prekunark - they only cast < kunark or velious
kunark - prekunark + kunark
velious - prekunark + kunark + velious

Not a big deal now since Velious will release soon, but for any server releases in the future, it will be correct.
