Add Crystalize Mana PE icon, allow radius enchantments to trigger CM. Fix an error in Distill. Fix Jala herald shields to actually give Jala spellpower.

Crystalize Mana will now display an icon while triggered, similar to Second Wind. Also when a player runs out of mana due to casting a radius enchantment (and they have the CM spell) they will trigger it and can keep singing, rather than drop all current radius enchantments.

Also fixed an error in Distill where for some reason a variable was holding a value other than $ when nothing had been assigned to it. Seems we have to initialize our variables if it is possible nothing will be assigned to them?
