Title: Respond to empty username and password like any incorrect credentials.

I didn't tweak the UI to disable the login button unless the username and password fields are non-empty, because that kind of code just is more stuff to go wrong. I can do something like that if it's deemed preferable - but having the lower-level handling accommodate the server's eccentricities is a good thing, anyway.

(One might ask why the web API responds to an empty username and password with a 200, but we already know the web API is, peculiar.)

Fixes #509.
