Add a test page that uses FreeMarker servlet to use an ".ftl" file as a layout page.
Changed completely the nature of the issue.
There is no need for a FreeMarker module, since FreeMarker itself provides a nice support to JSP tags.
Tiles 2 works with FreeMarker!
Added a test case to the test webapp.
Issue closed due to the release of Tiles 2.0.5
