auto-move-windows: make the suspend and hibernate items configurable

Desktop users rarely use suspend, and in general hibernate is
more trouble than it's worth to show at all times, so make their
visibility configurable in GSettings.
Supend defaults to true (since that's the GNOME 3 message anyway),
while hibernate is normally false. No UI is provided, since it's
unlikely that changing this is necessary.
