Added the documentation for the new MetacatUI theming mechanism. Make some styling changes to the documentation and configuration pages and added Bootstrap and FontAwesome.
FontAwesome and Bootstrap are imported locally rather than via CDN. Updated the docs screenshots to the new style.
Pull the external stylesheets in by <link> rather than @import for faster page load
Matched the admin config pages to the default metacatUI theme. Changed the background image of the docs and config pages to a big cat for some metacat branding.
Redesigned the /admin configuration pages to better match our new MetacatUI design. Looks good in both /context/admin view and the #external view using metacatUI
Change location of PropertyService to properties directory
Add backup configuration page
