	- Ticket #833: Add support for QuestIcon added with 4.0.x.
	- HolyPower: Limit watching PLAYER_LEVEL_UP to when needed.
	- SoulShards module shouldn't show until level 10 on Warlocks.
	- SoulShards should clear on PLAYER_ENTERING_WORLD.

	- HolyPower module should only show for Paladins at or above level 9.
	- Ticket #846: HolyPower should clear on PLAYER_ENTERING_WORLD.
