Domen Kožar 65a28e8b73 Add gnome3 desktop manager. Very experimental.
Currently very basic gnome-shell launches on my laptop. Quite some
services won't start yet, most notable is gnome-control-center.

GTK3 apps still don't have theming applied and for example launching
chromium results in horrible red windows.
