Stanza objects now accept the use of underscored names.
The CamelCase versions are still available for backwards compatibility,
but are discouraged.
The property stanza.values now maps to the old getStanzaValues and
setStanzaValues, in addition to _set_stanza_values and
_get_stanza_values.
Implemented ANONYMOUS authentication on the ClientXMPP class.
To use it, you just need to provide a domain (e.g 'anon.example.com')
with an optional resource (e.g 'anon.example.com/resource') as the JID,
with no password. The JID class has been improved to accept
domains as fulljid.
You can test this with echo_client.py
python echo_client.py -j anon.louiz.org/ # anonymous with a resource
# defined by the server
python echo_client.py -j anon.louiz.org/resource # anonymous with given
# resource
The "normal" authentication method still works exactly like before.
