James D. Callahan III:
	- Replace the value of private.OverlayKeyColors with _NPCScanOverlayKeyColors on ADDON_LOADED, so the configs will work.
	- Restored assignment to _NPCScanOverlayKeyColors of private.OverlayKeyColors - this is a SavedVariable that allows users to set custom NPC colors.
	- Revert "Removed _NPCScanOverlayKeyColors from the SavedVariables line. Why the hell was this even here to begin with?"
	This reverts commit d05cd4f3e727322c4e131b5e585270b788d977eb.
