command line: add `seed` command

[feross]

start seeding a file like this:

webtorrent seed /path/to/file.txt

This would be great! Is there another way of seeding at the moment with cli?

[feross]

Currently there's no way to seed with the webtorrent command line program. That's what this issue is for :)

You can always use the client.seed API directly from a node.js script. Docs for it are here: https://github.com/feross/webtorrent#clientseedinput-opts-function-onseed-torrent-

Okay, this is done now. Still only seeds to bittorrent nodes. I'll add seeding to web peers soon.

Released as 0.25.0.
