Update the admin interface and demo site generator
Update the admin interface and demo site generator

Update the admin interface to feature a fully responsive, fully retina, cleaned up look and feel based on Bootstrap 3. Simultaniously updated the generated demo site to be more in line with what we use as a starting point for our websites.

While this commit is squashed under my name, this is the result of the hard work by too many people to mention by name.
