Assigning this to gnome-session

(16:31:46) chrisccoulson: What should be responsible for locking the screen when a user suspends their machine from gnome-session now?
(16:32:21) chrisccoulson: gnome-session used to ask g-p-m to suspend the machine, which used to lock the screen, but that doesn't happen anymore now gnome-session uses dk-power directly
(16:33:46) hughsie: chrisccoulson: gnome-session needs to tell gnome-screensaver to lock
