Hendrik Leppkes:
	- Add sec:curpp/abscurpp/curmaxpp/absolutepp tags, a generic version of the druid:* tags
	- Revert "Add a new set of mana:*pp tags to always show current mana"
	This reverts commit a0f76bf3b0c660038a07f75b7d0d354c6c89c8b1.
	- Add a new set of mana:*pp tags to always show current mana
	The normal *pp tags always show the primary power type, like Insanity or
	Maelstrom on S-Priests and Shamans. These tags allow getting a clear mana
	value.
	- Force a power update on PLAYER_UNGHOST to catch resurrecting after a corpse run
	- Fix deleting the last aura from a group
	- Add safety checks to ensure aura config is setup properly
