Specialization for extended design configurations and register new configurations.

Author:		Ifko[nator]
Datum:		21.07.2017

Version:	v3.0

History:	v1.0 @ 28.02.2017 - initial implementation - added possibility to change capacity via desingConfiguration
			------------------------------------------------------------------------------------------------------------------
			v2.0 @ 25.03.2017 - added possibility to change rim and axis color via desingConfiguration
			------------------------------------------------------------------------------------------------------------------
			v3.0 @ 21.07.2017 - added possibility to change fillable fill types and cutable fruit types via desingConfiguration
