Cargo.toml:  Bump crate version to 0.4.0; this makes more sense to keep it in line with the old repo's semantic versioning

src/lib.rs:  Make `mod client` private, but `pub use` client::Client, client::torrent::Torrent, and client::torrent::TorrentFile

src/client/torrent.rs:  + GetTorrentFilesRequest, TorrentFile, TorrentFileWrapper, and GetTorrentFilesResponse

src/client.rs:  Client::list():  Put hardcoded field list here and use it with FieldList::from_vec()
