  Hier wird das Menu von Navigation erzeugt
  Dazu wird eine rekursive Funktion verwendet, so daß die Schachtelungstiefe beliebig ist.
  Erzeugt wird eine <ul><li>-Struktur die mittels CSS formatiert werden kann.
  Zudem wird eine Call-Back-Funktion aufgerufen, mit deren Hilfe zusätzliche Menüpunkte
  dem Menü vorangestellt werden können.
  
  Hinweis:
  Hier kann die Funktion mandalay:getColorset nicht verwendet werden wenn die verschiedenen
  Menüpunkte in ihren jeweiligen Farben eingefärbt werden sollen.
