Dalt Algorithmus und Auslagern des Displays

Der Dalt Algorithmus wird nun von dem Dalt-Button ausgeführt. Gleichzeitig wurde die Funktion showImage geschrieben, um Code zu verschlanken und lediglich die Switchfunktionen simulate und daltonize für die Auswahl der Simulationsart zu nutzen.
PS: Mehrere Bilder zum Testen eingefügt
