Fixed and improved jQuery's event system: The target property of the event object is now fixed (IE and Safari), bind() accepts now a third parameter "amount" to run the function only the specified number of times, oneclick etc. uses this new bind - it removes the handler when it is not necessary anymore, therefore providing better performance, see accordion for test/demo ( joern.jquery.com/accordion/accordion.html )
