Update SSL protocol for Deluge connections

Since Deluge 1.3.10 the SSL protocol is updated to TLSv1 instead of SSLv3. This resulted in CP not being able to add new torrents. Link to change in Deluge: http://git.deluge-torrent.org/deluge/commit/?h=1.3-stable&id=26f5be17609a8312c4ba06aa120ed208cd7876f2
