Display more information displayed when viewing Unsubscribed list

In the "contacts report" for "contacts unsubscribed", it would be really healpful to include the campaign that an unsubscribe came through in order better understand when and why contacts are unsubscribing. Additionaly including the "date unsubscribed" and "reason unsubscribed" would also be helpful. Adding these fields tot he report would help us to get an better birds eye view of why we are losing contacts. Only having access to these details when looking in a specific campaign limits visibility of larger patterns.
