  Newsticker
  Methode:	Ein äußeres <DIV> sorgt für die Position auf der Seite
                Ein inneres <DIV> sorgt für einen umlaufenden Abstand
                Darin befinden sich untereinander zwei weitere <DIV> mit den Inhalten
                Die Positionen dieser beiden <DIV> werden beim Scrollen jeweils um 1 vermindert, bis das obere unsichtbar ist. Rhythmus 10 ms.
                Dann wird das obere <DIV> unten an das sichtbare angehängt, es bleibt dabei weiterhin unsichtbar. Die Positionen werden also getauscht.
                Abschließend wird in das untere <DIV> der nächste Text geschrieben.

  Parameter:	Breite und Höhe des Bereiches lassen sich angeben, inclusive Rand an allen Seiten
  		Randbreite ist definierbar
  		Hintergrundfarbe ist definierbar
  		Hintergrundbild ist definierbar
  		Scrollintervall ist definierbar
