Added extra options to the 2 main healing spells; Flash of Light and Holy Light.
In the screen shot, both Flash of Light and Holy Light are set to the same health %. But Flash of Light will only be cast if you have adds, and Holy Light will only cast if you have Crusader buff (check by ID). If none of those conditions are met you're kind of screwed, but you get the concept behind the additional options.
The new conditions only apply IN combat. When out of combat the CC will heal based on health % using either Flash of Light or Holy Light, whichever % is lower. There is also a 'hidden' setting in the XML file that will override both these conditions if your health drops below an absolute minimum percent (currently 25%)
