Core/Items: Fixed proper FindEquipSlot on relics from n0n4m3's commit according to:

http://www.wowwiki.com/Relic

"In Cataclysm the relic system is simplified. Instead of four different types of relics, each one only usable by one class, all relics will be usable by any class capable of using a relic.

While the items may contain the words Idol, Libram, Totem, or Sigil in their name, they will not be sub-categorized as them. "
