SpellTips

Updated all English spells for WotLK and cleaned up the code.

Translations all need updating but I'm not going to update any of them until someone asks for their particular class/language combo to be updated.
Most spells will still display numbers lower than they actually do because there's too many variables to account for.
Glyphs are not supported and I have no plans to support them because although some glyphs are very straight forward in the effect they give, others drastically change spells and would be a nightmare to accommodate so I'm discriminating against them all.
