Whenever an 'admin' route is detected, show gr-admin-view, with a
sub-view in the main content area. This allows a single
sidebar to be shared amongst all admin pages, and allow easy navigation
between sections.
The 'more' dropdown is now just a link that goes to the first admin
item (project list). Design was concerned that there were too many ways
to navigate between sections otherwise.
Future changes will include:
- Mobile consideration
- Dynamically Updating project/group specific pages when viewing a
project or a group
