slaren:
	- fixed type in the spec detection code
	- castbar: fixed some problems, unified the frame so that there is only one attach point for it
	- fixed error when moving the frames
	- party and arena are now configured independently from each other, unfortunately as a consequence of this some settings will be reset to their defaults
	- check opponent specs on ARENA_OPPONENT_UPDATE, should help detecting specs when ARENA_PREP_OPPONENT_SPECIALIZATIONS is not fired (happens if not everybody joins the arena)
	- clicking on the anchor with shift/alt/control now centers the anchors around different targets
	- changed some specs of the test frames
	- core: added "up and down" grow direction for centering the frames vertically, fixed a few problems with the layout code such as the background not working with some grow directions
	- cooldowns: more changes to ensure pixel adjusted borders
	- drtracker: moved grow direction option to the widget section
	- cooldown: adjust border size to the frame scale rather than the uiscale
