Adds the command `imdl` torrent verify` to verify the contents of torrents. This implementation is extremely naive. It does successfully verify torrents, but it will produce unsatisfying results when a torrent fails verification. In particular, it won't give any information about which pieces in a file were corrupt. type: added
