Cleaned up resonsive for the rest of the remaining pages: the dash
index, page index, page editor, navigation editor and plugged in a
mobile nav that activates when the viewport gets skinny.
Whew.
First pass for CSS refactor for the dashboard, including the login and
index templates. Still rough but the basic structure is in place for
both as well as the re-worked css that will be added to the repo later
once all the pages have been updated.
Lots to do still but a good start.
