[libtorrent] patch: docs/reference-Session.html (dht_put_item)

[Angel L. <gub...@gm...>]

I think there's an important typo on the mutable `Session::dht_put_item`
documentation. (the dht_put_item function that takes a key and signature is
meant for mutable puts, right?)

Is this the way to collaborate with the project? (sending .diff files?)

It'd be awesome if we could collaborate via git/github.

A synced repo with all the svn history on github.com is ready for you guys
to just create an official fork.

Would be so much better to collaborate and grow this wonderful project.

Best,
Angel
