Proposed patch to enable RSS feed generations.
This patch uses the new changes model, as given in
TODO : Are those really the significant RSS feeds we want to generate?
TODO : Look more closely to the changes-actions-rss.xml feed, and wether or not it should be generated, depending on the current Version of the project. A snpashot version of the project should generate this feed, as well as a alpha/beta release while a stable one should not. Depends too on the fact that the most recent release in the changes.xml is not necessarily up to date with current Version of project.
Anyway, this patch is more food-for-thought than a working patch.
Futher work should be delayed until
MCHANGES-47 model is accepted or refused.
