WowAce

Wrath-related fixes:
- updated for beta build 8820. IceHUD will start up correctly once again
- updated SunderCount/LacerateCount modules to use the new UnitDebuff return values in wotlk properly/register the changed wotlk events
- updated SliceAndDice module to use the new UnitBuff return values in wotlk properly/register the changed wotlk events/new combo point parameters
- updated DruidMana module to update every frame in wotlk since the other mana frames need to...this still needs dogtag to be updated to work fully in wotlk
- updated ComboPoints module to use the new combo point functionality and events in wotlk

Non-wrath-related fixes:
- updated SliceAndDice module to be more efficient outside of combat (avoids unnecessary OnUpdate stuff)
