I've renamed TorrentManager to ArchiveManager, ArchiveManager to ArchiveFileManager, TorrentContract to ArchiveService, ArchiveContract to ArchiveFileService. I've also renamed all init functions and struct fields to the appropriate archive-centric naming.
To be honest once I started this work I quickly realised how pointless it is as archiving functionality and torrent seeding functionality are really entwined. So I'm keeping the code I've done but it is a bit pointless without spending a lot of time untangling torrenting and archiving. I'm just going to make an interface for all the functions that are used publically from TorrentManager. I think that this will be the fast way to move on from this issue. I don't like this work any more, there is a lot of work to do elsewhere and torrent is a rabbit hole filled with canned worms.
