Erste Version von PersistentScale

Folgende Punkte funktionieren:

 * Hinzufügen, Editieren, Verschieben und Löschen des Widgets
 * Bearbeiten der Optionen für die Skalen (Hinzufügen, Editieren, Löschen)
 
Funktioniert noch nicht:

 * Hinzufügen von Fragen - Zur Zeit sind da 3 Dummy-Texte eingebaut, um die eigentliche Ausgabe zu testen
 * Ausgabe der Zeilen (Frage plus Skala) erfolgt noch nicht im richtigen Format
 * Noch keine Anzeige auf der Webseite (keine Ahnung warum, ich dachte, daß sollte funktionieren,
   wenn die Ausgabe im Form-Editor funktioniert)
 * vermutlich viele andere Dinge
