Hey Jon,

This update adds the input-search taglib to the portlet in both the main search and the results screen.  For the cancel button functionality, I added an attribute flag to the input-search taglib that allows the user to add the input-search field as a target for the A.ButtonSearchCancel module.  This functionality is completely dependent on an additional method in the AUI module, since to accomplish this I had to automatically instantiate the module in the bottom_js.jsp.  The mobile-only functionality of the module is still present.
