Added a license (and my email address).
Extensible library for handling the XMPP protocol (RFC 3920). This
code is inspired by, but not derived from,
https://github.com/mattn/go-xmpp/.
The core of the protocol is handled by xmpp.go, structs.go, and
stream.go. Everything else is an extension, though some of the
provided "extensions" are mandatory pieces of the protocol.

welcome. The license is in LICENSE.txt; it's a BSD 2-Clause license
