The model-free user function class now has a menu icon.

Converted the molecule user functions to the auto-generation design.

Created a basic icon set for the model-free theory.

The failure of the user function page on_display() method now prevents the wizard from being displayed.

The Uf_page.on_display() method now gracefully handles RelaxErrors from the uf arg iterators.

This now catches the error and uses gui_raise to report to the user.

The Uf_container object can now have the 'desc' variable set multiple times.

This allows for molecule user functions where the generic_fns.mol_res_spin.ALLOWED_MOL_TYPES list
values are appended to the description.

Big improvements for the Combo_list GUI element.

The client data is now set and returned instead of the string values, allowing for more descriptive
choices. The SetValue() method has been implemented. And floats and ints are now supported as data
types.

Fix for the Value.ResetChoices() method for ComboBoxes for handling non-string types.

Converted the model_free user functions to the auto-generation design.
