Login with empty text of password.

hi,
Thanks for this project. It really help me a lot.
But I found out that if I login with an empty text password, it will not be able to login and type account and password again until restart my browser(Chrome).
I think that is because Chrome remember basic-auth with my empty password.
So I add a if addition myAuth.pass !== "" on WebSSH2/app/server/util.js:12

var myAuth = Auth(req)
if (myAuth && myAuth.pass !== "") {
    req.session.username = myAuth.name

And now the input box of login will appear again just like inputing a wrong password!

Okay, I see your problem here... I think I need to solve it a different way, because it's entirely possible that one could have a blank password... PermitEmptyPasswords is a setting in OpenSSH. Let me take a look at this.

And, it should re-prompt if you after a failure, if you have the allowreauth option set to true, which it currently does not. The problem is in my logic. Standby.

Okay, I need to spend more time on that to support a blank password, for now your suggestion will work fine.
