[Catalyst] OpenID authentication

[Benjamin Trott]

Hi,

I just uploaded to CPAN version 0.01 of
Catalyst::Plugin::Authentication::OpenID, which provides support for using
OpenID auth in Catalyst apps. More about OpenID: <http://www.openid.net/>.

It plays well with existing session plugins, and in fact, is recommended to
be used alongside any of the session plugins. From the synopsis:

    use Catalyst qw( Authentication::OpenID );

    sub begin : Private {
        my($self, $c) = @_;
        if ($c->authenticate_openid) {
            my $identity = $c->req->{openid_identity};
        } else {
            $c->res->redirect('<your-login-screen>')
                unless $c->res->redirect;
        }
    }

Hope this is helpful. I know it's been pretty useful in building some demo
apps internally, so we figured it was generally useful for building apps
without having to worry about building explicit authentication. Thoughts?
