loginScreen: reset greeter when coming back to login screen

When a user logs in to a wayland session, we keep the login screen
running on the X server with the login screen running in a deactivated mode.

This commit makes sure it get reactivated when the user comes back to
the VT (from user switching, logout or just ctrl-alt-f1).

Patch needs work to fade actors back in.

attachment 272818 [details] [review] adds the actor fade back in (though I didn't update the commit message).  It's not reliably working though.  When mutter failing to drop master on leave vt for me:
