Event-listing portlet fixes and updates

Hi Jesse, Rich

I had broken the portlet's JSPs by mistake. When I ran 'ant format-source' from within Liferay IDE, it tore out the imports from init.jsp. I'm not sure if this is an IDE problem or if the same thing happens with the target from the commandline. In any case, I retested the portlet successfully on Beta1 and updated it and the SDK. I left all the formatting changes done by the target, except those tear-out of the imports from init.jsp.
