Shadowed:
    - General code clean up, updated some out of date comments made some code a little less evil and such
    - UNIT_AURA now checks guidToUnit instead of UnitPlayerOrPetInParty/Raid, prevents HealComm_ModifierChanged from firing without a valid unit in the map
    - Fixed players equipped relic not being reset when unequipped
    - Fixed parseDirectHeal and parseChannelHeal using the casters name rather than the GUID + unit in the mapping table
    - Fixed spell rank being set to nil if it equals "", UnitAura returns "" rather than nil for spells with no rank
    - Fixed a few data tables being loaded on new instance rather then persisting
    - Fixed no HealComm_HealStopped event firing if someone leaves a group while they have active heals (Need to test)
    - Fixed averageHeal having multiple metatables being set on it if you had a LoD instance load (Can you do this?)
    - Removed unnecessary function declarations
    - Removed LibStub reference due to CallbackHandler-1.0 loading it already
    - CallbackHandler-1.0 seems to embed LibStub and load it through the XML file, so removing the LibStub embed
    - Quick change to make sure GetRaidDifficulty exists as the Chinese version of WoW is still on 3.1.x it looks like
