Don't include override-redirect windows in the list return by meta_display_list_windows(), since we almost never want to handle them when considering "all window" for the display. Add a separate meta_display_list_all_windows() that includes override-redirect windows. http://bugzilla.gnome.org/show_bug.cgi?id=582639
