Fix fullscreen spanning multiple monitors

Commit a16635c ("Fix fullscreen - remove all the garbage
which breaks things and let Gtk do its job.")
broke fullscreen spanning multiple monitors.

Fix this for GTK3 by using gdk_window_set_fullscreen_mode().
Fixes #650.

Unfortunately, GTK2 has no equivalent.
