[NNTP] Case sensitivity

Hmm. So:

    aUtHiNfO sAsL PLAIN weeble

is fine but

    authinfo sasl plain weeble

isn't.

You could allow it to be case insensitive (thus requiring the server to
uppercase the method internally). But it's not a major point; I'll leave
it up to you to decide where to go with this.
