Rework some Spell AI so NPCs can have spammy spells

Browse Source 
Lots of encounters in EQ will spam spells, like dragon fear is on a very
tight timer etc. In order to eliminate the need to script all of these
encounters AI spells with a priority of '0' will be treated as "innate
spells." Devs have used this term and it is what I believe they mean by
it.

You can run update npc_spells_entries set priority = priority + 1 where priority >= 0;
to disable the behavior.
