jquery bug fixes / refactoring jquery + erb/routes

This was not working because it really looked for two events.

This first one looked for a click event on the "extras" DIV, which then prevented default. Then it fired one of the functions in the if statement, which also prevent default on yet another click for the element which has the unMarkFavorite or markFavorite class. It thus required two clicks in order to make the DB call and change the link.
