Adding a protocol to the <link href=""> for the external CSS

add anchor for plugin handlers property

Pull the external stylesheets in by <link> rather than @import for faster page load

Simplified the importing of images and stylesheets so that both /admin and /docs pull from /docs

Made some CSS changes to the "Go" button in the docs because it was off by a few pixels in three different browsers. Also changed the admin config landing page links to look like buttons

add documentation entries for fields that appear on the main metacat admin page.

Imported FontAwesome after Bootstrap for the FontAwesome icons. Also added a white version of the metacat logo.

prep for 2.2.0 release. include configuration value for metacatui deployment context.

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.
