As it is right now, if cloning existing page elements is performed in setContent, their event handlers get blown away when the $tip is attached to the document.
This patch would allow other components to extend setContent and clone ($.clone(true)) nodes into .tooltip-inner, and thus clone events as well.
In combination with trigger: 'manual' this would allow one to create pop-up menus containing buttons (and make them work with frameworks such as Backbone and KnockOut.js).
