Option to delete transcode and .torrent after copying (or just move)

Source: #77 (comment)

Also the current workflow (discussed here) leaves a lot of trash around that's kind of a pain to clean up. If i'm copying the torrents to another location for auto-add why is it leaving the original behind? why is the .torrent used to check for transcodes not deleted?
