Adding private tracker torrents broken

[DanielBaulig]

Adding torrents from private trackers through a click on the icon does not work. I suppose it is, because the torrent is downloaded remotely and not locally on your machine. To download a private tracker torrent you usually require to login to the tracker, so the torrent will not be available to download if you are missing the required cookies.

How to fix:
Download torrents locally and send the downloaded torrent file to deluge. This way the user can log in to the tracker locally and the plugin can "ride" the users session.
