Shadowed:
    - Added configuration of the alt power bar
    - Improve the alt power color to be more distinctive
    - Don't let alpha be set on power colors, it never actually did anything, I'm just removing it so it's clearer
    - Fixed bars that are hidden by default (alt power) not working due to not being initialized
    - Fixed vehicle frames swapping when unneeded due to Blizzards alt power vehicle insanity
    - 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
