Mark added/deleted binary files
When I look at a changeset with added and deleted binary files, hg-review just shows an empty diff. It would be nice to know the status of these files, i.e. added/deleted, maybe even a "copied from" comment. This information is available in the diff header that is currently just thrown away.
The best UI I could think of for that would be to add a text after each filename that says "(added)", "(deleted)", "(changed)".
