*implement new creatureAI called: AOEAI

-it takes the spell1 from creature_template and casts on him self if aura not found, it can not attack or move
-creature becomes unattackable and invisible
NOTE: flag 128 should not be set in flags_extra field in creature_template, otherwise spells will be only visible to GMs
