    main: Fix warning on Alt-Tab
    
    Alt+Tab'ing the window after starting totem without any movies throws
    an error:
    (totem:511152): Gtk-CRITICAL **: 18:12:59.499: gtk_widget_event: assertion 'WIDGET_REALIZED_FOR_EVENT 
(widget, event)' failed
    
    The widget in question is BaconVideoWidget for which we removed an explicit
    gtk_widget_realize() while doing the GL port.
    
    Reinstate that call for GTK 3.
    
    Closes: #503
