#9 no username, only password

[A Mennucc]

hi, I was looking into the authentication method, and I noted that , in a sense, there is no need and no usefullness for having both a 'username' and a 'password'. Indeed, both are tokens that are passed and checked in the daemon.

I would propose, before SVN is released as version 2, to delete the 'username' and only have the 'password'.

If you agree, I may write the patch.a.
