[sc0ttkclark]

• [x] Method to register config for widget form fields (return array?)
• [x] Widget form parent method should look for fields config, if set, output the form fields
• [x] Widget update parent method should look for fields config, if set, process saving of the form fields

From @nicholasio:

based on your user-fields implementations before outputting the controls, I’ll use the helper methods of the widgets class to define the name and the id's of the control, because this will make easier to save the data, as the data will come through $new_instance, and I’ll only need to sanitise the data

@nicholasio

I looked over your widget code and I think there’s some more things we can do:

1. Add a new class like WP_Widget_Fields_API or something, which extends the WP_Widget base class, so we can add some more object oriented code
2. saving / etc is now done in the user implementation, you can see that for what you need to do there
