UI needs to display the audit history for the currently selected setting

[ciroque]

Below the sections that show the hierarchy and edit fields there needs to be a list that is populated from the audit catalog that shows all the changes made to the currently selected setting. If no setting is in context the list should be empty.

When items exist in the list it should be possible to select an entry. Selecting the entry will display the details of the audit record. This includes he before and after values as well as the date / time the change was committed.
