Catalyst::Authentication::Credential::OpenID now supports -- thanks
to Martin Atkins -- OpenID 2.0 as well as 1.1. Thanks to a patch from
Menno Blom, C::A::C::OpenID also loads Simple Registration (SREG)
data when it's present/configured.
I am not using this in the wild right now so I'd really appreciate
any bug/problem tickets or Pod patches. If there are OpenID
extensions other than SREG which anyone is using, please let me know
so I can look at them and see if/how they can be supported.
