The GUI user function on_execute() method no longer shows the controller in test suite mode.

The controller Raise() method was being called at the end of the method, without checking
status.show_gui!!!

Fixes for the Rx auto-analysis GUI test for the new auto-generated uf design.

The GUI tests base class execute_uf() method will now try to set all keyword args.

This allows the user functions with free file format keyword args to be operational.

The Combo_list GUI element now handles the wiz_combo_list_min uf arg arg.

If not enough elements are set, Combo_list.GetValue() will return None. This is caught by the auto
-generated GUI user functions on_execute() method, preventing the execution of the user function.

The spectrum.replicated user function back end now checks for lists of None or of 1 element.

Renamed the user function arg arg wiz_combo_list_size to wiz_combo_list_min.

This will be used by the Combo_list object to ensure a minimum length.

The Rx auto-analysis peak loading wizard has been converted to the new auto-generated uf design.

Individual elements of the Sequence and Combo_list GUI element can now be set via the SetValue() method.

The Sequence.SetValue() method now accepts the index arg, and this is passed onto the
Combo_list.SetValue() method. The individual elements of the Sequence element still cannot be set
via the index.

The free file format object can now be remotely controlled in the auto-generated user functions.

This allows the test suite to set these values. For this, a special Free_file_format.SetValue()
method was created, and the user function SetValue() method will call this when needed.

Removed the desc_short args to the Sequence* GUI input element classes.

These do not exist!
