Created a GUI element for listing and setting the scripts used in the analysis.

This will be used in the BMRB export window.

The GUI user functions now have a subtitle at the top stating the name of the user function.

This is to reinforce the user function naming system to the user, and also to clearly identify which
window belongs to which user function.

Renamed the _override() method to setup().

Split the software GUI element into the base_list base GUI listing element.

This base class will be useful for abstracting many of the list GUI element methods.

Edits to the software listing GUI element.

This allows long lists to fit much better into the wizard windows.
