Allow reverting of delete file commits
Once a file deletion has been committed, it is extremely difficult to undo this. The only way I managed to do it was to find the revision where it occurred in the History Viewer, choose "Revert changes from this revision" (thereby reverting all the changes done there) and then again reverting the other changes.
Much simpler if I could select the "delete file" action in the History Viewer's changed paths and choose "Revert".
