Shadowed:
	- Force enable the alt power bar for everyone due to issues with the player one sometimes not working due to *mysteries*. Disable it under Hide Blizzard if you really want it hidden still.
	- Player alt power should be enabled by default, fixed a conflict between DB defaults and layout defaults
	- Tweak the visibility manager for default state to not let default hidden bars show up randomly
	- Only do the type check if an event is passed
	- Actually revert that
	- Only do alt power checks on player units
	- Do a display check on alt power when UNIT_DISPLAYPOWER triggers
	- Switch alt power to use non-frequent and frequent updates for the time being
	- Update alt power bar to handle inverting/overrides and function like a normal bar
	- Check alt power on PLAYER_ENTERING_WORLD
