ChangeLog:
The selector engine now returns elements in document order rather than the order in which the selectors were passed in. It's now possible to call "event.stopPropagation()" or "return false" within a .live() callback and have it stop the bubbling of the live event. The logic behind the :visible and :hidden selectors and the .height(), .width(), .innerHeight(), .innerWidth(), .outerHeight(), and .outerWidth() methods was overhauled. The methods appendTo, prependTo, insertBefore, insertAfter, and replaceAll all now return the set of inserted elements, instead of the original set of elements.
