 * ClickListner Methode fuer die Reaktion auf Buttonclicks. Hier wird

 * reagiert, wie auch auf jene die Projekte loeschen. In der ersten
 * If-Abfrage werden die vom Hauptfenster ausgeloeten Clicks zum Hinzufuegen
 * eines neuen Objektes behandelt, in der zweiten If-Abfrage wird die im
 * Dialogfenster ausgeloesten Clickst behandelt (Hierbei wird noch geprueft
 * ob das auf "required" gesetzte Textfeld auch ausgefuellt wurde - falls
 * nicht wird eine Fehlermeldung angezeigt) und in der Else-Verzweigung dann
 * die Loesch-Clicks fuer das jeweilige Projekt behandelt. Hierbei wird
 * zunächst durch das Event in der Loesch-Buttonliste der Index
 * identifiziert, also welches Projekt zu loeschen ist. Die jeweils folgende
 * Logid ist in der je aufgerufen Methode des Presenters zu finden.
