Bug 1180125 part 4 - Move PseudoTypeAsString to AnimationCollection and reuse; r=dbaron Prior to this patch, CSSAnimation defined a method for converting an nsCSSPseudoElements::Type to a nsString (but only for the set of pseudo-elements that can have animations). We would like to re-use this when setting up transition events so this patch moves it to AnimationCollection. Re-using this method more widely means we can make a few further simplifications to the code.
