Hendrik Leppkes:
	- Update for Cooldown changes in 7.0.3.21796
	- Remove redundant charge position set
	This is already done when an overlay is retrieved from the storage
	- Support skinning the charge cooldown frame with Masque
	- Treat spells with one maximum charge like spells without charges
	These spells usually get a second charge through a talent or glyph,
	in which case they will be handled as spells with charges again when
	this talent/glyph is chosen.
