Clean up custom fields view for radio and checkbox types

Right now, when you view custom fields for a contact, if a field is a radio box or a check box field, you see all of the options for that field, with a small "x" indicating which one(s) are selected for the contact.

This can get pretty cluttered and confusing if you have many options or custom fields.

Ideally, the custom field view would only display those values that have been selected. So, if a check box field Type of Matter has the options Animal, Vegetable, and Mineral, and only Vegetable is selected, it would be displayed "Type of Matter Vegetable" instead of "Type of Matter [ ] Animal [x] Vegetable [ ] Mineral." Much cleaner and easier to read and understand at a quick glance.
