[glom/glom-1-24] Avoid a crash at shutdown.

[Murray Cumming <murrayc src gnome org>]

commit cead47965183a819e237c345e2136c547be50355
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Sep 11 10:24:45 2013 +0200

    Avoid a crash at shutdown.
    
        * glom/bakery/appwindow_withdoc.cc: on_menu_file_close():
        Close the document after hiding the UI, instead of the other way
        around because, with Gio::Application, hiding the window can cause
        it to be deleted, making any further use of it impossible.
