Every column has to be in a row, and every row has to be in a container (except
where a row is nested directly within a column).
This also includes a change to index.html that pushes the footer to the bottom
of the page on those where it otherwise wouldn't be.
* Created a new Python/flask-based management daemon.
* Moved the mail user management core code from tools/mail.py to the new daemon.
* tools/mail.py is a wrapper around the daemon and can be run as a non-root user.
* Adding a new initscript for the management daemon.
* Moving dns_update.sh to the management daemon, called via curl'ing the daemon's API.
This also now runs the DNS update after mail users and aliases are added/removed,
which sets up new domains' DNS as needed.
