Stil wählen, merken und fotografieren

F2 wechselt im Spiel den Stil und meldet ihn, --style=NAME wählt ihn
beim Start, und das Spiel merkt sich die Wahl in den Einstellungen.
Das Bildschirmfoto-Werkzeug nimmt Bilder in einem bestimmten Stil und
von der Vitrine auf und zeigt eine zweite Figur mit Namen.
