Title: Using jQuery 1.7 $.on if available

Uses the new $.on event handler (if available) rather than $.live. This should hopefully lead to better performance and less problems related to bubbling (as sometimes seen with $.live). It still uses $.live for jQuery versions < 1.7. For more information on $.on see http://blog.jquery.com/2011/11/03/jquery-1-7-released/.
