Shadowed Unit Frames Redux

-2D portraits now fill their area without stretching, the image is cropped to fit.
-Range spells no longer need to be castable, only known.
-Fallback to a 28 yard interact check when no range spell applies.
-Forever : warriors, rogues and hunters use the 28 yard interact check instead of spells with a minimum range (you can still add a spell if you want to).
