AdiBags Item Bonuses

This is an extension for the WoW addon Adibags, which adds additional filters (item groups) based on if an item has any bonus stats. Filters are configurable using AdiBags options, and in the future, combinations of stats will also be selectable (eg, Crit + Haste / Crit + Mastery, etc). The filters only apply to current expansion items as this is when they are most relevant.
