We need to separate our site into two pieces: One for the ManifoldCF project, and one for each release

Part of the ManifoldCF site has to do with the ManifoldCF project, and part of it is germane to a given release. We should separate these so that the project-related part builds separately, under "site/trunk", and references one (or more) release-related sites, under branches/XXX/site.
