All pattern sublcasses contain the same code for handling the
feature list. This code is now moved into the base class that handles
the common ui.
The subclasses now only need to call the setupUI/setupParameterUI function
in their constructors and implement the setupParameterUI function
to create their parameter ui into the specified widget.
The MultiTransform also handles it's common ui and the subclasses
can reuse setupParameterUI without code duplication.
