systemd user session integration (Auke Kok)

[Raphael Groner]

Hej Auke,

FYI, there's already an open RFE bug for systemd.

https://bugzilla.xfce.org/show_bug.cgi?id=8729

Please consider to do the discussion there to lower traffic on the ml.

Thanks for your motivation to work on systemd.

R.

> - dbus activation for services that are dbus based (xfconfd)
