Creating a Simple Admin UI

This is a relatively small refactor to add a persistent header and style across all of the admin pages (at least all of the ones that I could find).  

It includes bootstrap, and just uses the default table styles to provide a nicer interface for these pages.  The other goal is to make it easier for people to find the other admin pages.  You can see it here:
