BEP 19: WebSeed - HTTP/FTP Seeding (GetRight style)

[josecelano]

Relates to: #437

Many websites that list a BitTorrent download also provide a HTTP or FTP URL for the same file. The files are identical. A WebSeeding BitTorrent client can download from either source, putting all the parts together into one complete file.

The HTTP or FTP server acts as a permanently unchoked seed.

Add add url-list field to torrent files with the list of HTTP seeders.
