    Fix check for events on UI widgets
    
    Now that we create MetaWindow objects for override-redirect windows, we need
    to check all key press events to see if they are on GTK+ widgets, not just
    events that don't match a MetaWindow. This fixes a problem with alt-Tab stealing
    grabs away from the window menu.
