Ability to revert changes

Teampass already keeps a history log of changes, and shows old passwords in the log (I don't like that, but that's a separate issue)

It would be useful to be able to revert one or more changes to a password items, in case where a change was made erroneously and we want to recover the old item.  This would be for any changes - username, URL, attached files - not just password.  If Teampass could keep the last X versions of each item (a configurable limit) and allow them to be recovered it would be a good feature.
