Simplified the importing of images and stylesheets so that both /admin and /docs pull from /docs
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
add logout links to header and footer. https://projects.ecoinformatics.org/ecoinfo/issues/3761
Added header and footer sections that allow admin to log in as different user and to see user documentation.
