From c34ccc130e2a507c266ee54a163cdf3a5886d63d Mon Sep 17 00:00:00 2001
From: deva <deva>

Subject: Made a lot of changes, making it possible to entirely remove th
 config.php file from the project. These changes includes the creation of a
 new rss config module, the adding of some config vars in both the events and
 news modules.
