Further CMS setup

Added automated CMS navigation to the navbar

Note that there MUST be a layout called "default" for this to work.
Also, this is the simplest possible navigation, and doesn't handle
nested pages (yet).  It just shows the top level links from the first
site.
Improved automated CMS navbar listing (and documented it in the README)
