Update to work with Django 1.01 since teamplayer (default) supports it now.
Also use settings.py instead of settings_local.py which I now consider an
anti-pattern.
When I switched over from openrc to systemd I was being lazy and took
advantage of the fact that /etc/local.d still gets run as usual on
Gentoo. This commit finally does a proper(-ish) systemd startup using
(3) unit files.
