Allow users to be able to choose the metadata fields they want to have displayed in the listing for the main album view.

Dynamic range

If a user is not so bothered in having the Rating displayed but might want to have a different metadata field displayed the user should be able wants to deselect /select fields as well as drag and drop them in to the desired order.
