OpenID and Persona off again, temporarily

So the Wordpress OpenID plugin is completely broken with PHP 5.5, and the hack I used to have Persona create a new user account on my blog if you didn't already have one has kind of gotten outdated. So neither of those auth methods is much use for the blog any more. Accordingly, I've turned them both off for now, we're back to old-school WP accounts and captchas for those who don't have 'em, folks. Sorry!
