Subject: Anonymous authentication

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.
