Add deluge support to TorrentToMedia

Switched from uTorrent to deluge on my machine, so I've added support for linking with deluge in TorrentToMedia. Will now pause torrents in deluge before linking & calling sickbeard etc, then resume. Will also delete the torrent + data after completion if it is set to.

Tested on Windows/Ubuntu.

Also note that this using the daemon RPC API, not the JSON web api, which caused me confusion at first.
