NICK: allow servers and services to use RFC 1459 syntax (2 parameters). 

This patch allows servers and services to call the NICK command using the
syntax defined in RFC 1459 to register new users, with only two parameters.
See section 4.1.2.

Useful for some services packages, which emulate this protocol.
