gnome-display-properties and unity. Adding “primary” display checkbox

[SB]

Binary package hint: gnome-control-center

When working with two displays there is a question of which display is the "primary". In the case of Unity the primary display is the screen on which the launcher appears for instance. This property can be set using xrandr, but the gnome-display-properties utility does not give a GUI way to set this. This should be addressed.
This bug was also raised upstream (https://bugzilla.gnome.org/show_bug.cgi?id=588041), and was apparently solved for Gnome 3.0. With the Gnome 3.0 vs Unity thing going on, I think that a bug like this should be addressed within Unity as well (and as I understand cannot be resolved upstream).
