Upgraded to recent version of Bittorrent/BitTornado

http://sourceforge.net/projects/pingpong-abc/files/ABC-source/3.1/
Stripped irrelevant files for torrent creation (GUI, etc)
Torrent Creation: Add support for WebSeeds and simple filenames

Added WebSeeds aka d['url-list']=http://example.com/file to .torrent
files see http://www.bittorrent.org/beps/bep_0019.html

File name previously were name file.torrent.file.orig now file.torrent
Updated to new make_meta_file API. Removed transmissionrpc

Use params['url_list'] to add WebSeed to .torrent
That makes serving files with transmissionrpc obsolete. Clients can
directly download from the HTTP-Server

Use params['announce_list'] to add Backup Trackers
(see http://www.bittorrent.org/beps/bep_0012.html#order-of-processing)

Introduced BITTORRENT_TRACKER_BACKUP in appsetting.py

Recreate your .torrent files to update:
>>> from videoportal.models import Video
>>> for v in Video.objects.all():
>>> ...    v.create_bittorrent()
>>>
Merge pull request #15 from hubx/webseed
