Add option to add torrent to qBittorrent directly

[Zmegolaz]

Prior to this you had to create the torrent files in a watch dir, or import them into your torrent client manually. This change add support to push the torrents directly into qBittorrent, if that fails it falls back to saving the file on disk.

Little bit conflicted on this one. on one hand this is genuine functionality, on the other, this is a bit of a narrow feature. Also - do you have proof that this functions? This isn't a minor change.

Yeah, it's a bit narrow, I'm aware configuring a watch folder and saving files there works as well, as long as the save directory matches. I mainly did this because I wanted the feature myself, but thought I'd share.

I have a workflow where I add a torrent to qBt with a transcode flag, then a "torrent finished" script runs orpheusmorebetter, which creates transcodes and imports the newly created torrents into qBt directly. I'm not sure how to prove it works, but I've uploaded around 1500 torrents this way.
