Autobuild of dashboard overview plus various fixes

This adds a call in sphinx to automatically generate the dashboard
description pages.  It's a little bit of a hack, but works with "tox
-e docs" and the readthedocs build.  This means we don't have to have
an external job running a separate build of the dashboard overview
page.

A couple of other things to integrate this and make the docs more
usable; we use the readme as the main page, fix up the links, use
sections in the template and add a clickable link to the dashboard in
each overview page.

I'ved tested this with readthedocs which you can see at [1]
