    Fix bug 692972 - Make spin buttons commit values synchronously
    
    Two things done to fix this:
      o gtk_spin_button_set_numeric() used to force numeric input
      o Connect to the GtkEditable::changed signal and force the
        value update with gtk_spin_button_update(), causing the
        value-changed signal to be emitted synchronously and
        the new property value committed.
