-Refactor provided web resources inside the jar so that each theme provides its own css, image, javascript, page component and page template resources.
-Enhance the xml schema of portal object to set / store the available themes for each portal. The theme may also be user selectable if more than one themes are available and stored in a cookie.
-Enhance the resource provisioning methods in AbstractContentObjectResource class to take into account the selected theme for locating the resource template, return resources from the default theme if no theme has been selected by the user (assuming themes are defined for the portal) or fall back to existing behavior and ignore themes if no themes have been defined for the portal .
-Optionally refactor and fix existing deployment to work with the new theme feature.
