Eventlisting adt

I updated the portlet and the portlet project with the proper taglibs and taglib references in the JSPs. Now you should be able to use the default template, new templates, ... whatever you want.

Note, you will still get the following error when you manage the templates. But it doesn't harm anything. (I'll ask Eduardo about it)
