Xirvik .torrent to seedbox uploader per Xirvik Servers

This extension adds options to .torrent files to upload them automatically to a number of popular BitTorrent clients.
This extensions allows you to upload .torrent files to your remote torrent client from Firefox, so you don't need to download the .torrent then login into the client, click upload, select the file from your computer, etc. Just click on the .torrent file and select "Upload to...".

The upload is performed by interacting with the client's web UI.

The following clients are supported:

- rtorrent (using rutorrent to handle the upload)
- utorrent
- Deluge
- torrentflux-b4rt

The extension is generic. While we test it in our specific setup it's known to work fine with default installs of the torrent clients and interfaces.
