#11 AutoRegister won't let nicks change later

[Ben Damm]

AutoRegister doesn't allow you to send a NickCommand to
change your nick - it changes it right back as soon as the
server acknowledges your change.

The updateCommand method is at fault, and needs to
check the current state before making a change.

Fixed in CVS. updateCommand doesn't check the state, but it also
doesn't send a NickCommand in response.
