Further CMS setup

- started writing feature tests with capybara
- set up redirect after login
Added seeds for test1/2/3 users and admin1 user
Require admin user for CMS admin
Added license
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)
Merge pull request #5 from Skud/cms
