- add fgcommand to reload menubar; that's necessary to make changes visible

  at runtime. Example:

  <key n="99">
      <name>c</name>
      <desc>Update completely useless menu entry.</desc>
      <binding>
          <command>nasal</command>
          <script>
              time = getprop("/sim/time/elapsed-sec");
              setprop("/sim/menubar/default/menu[9]/label", time);
          </script>
      </binding>
      <binding>
          <command>menu-reload</command>
      </binding>
  </key>
