[PATCH] Make it possible, via a config setting, to use OpenID for authentication

Looks good, just one thing:

I'd prefer to show the register link along with the login link always -
it doesn't make sense to click on a 'login' link if you know you don't
have an account (or don't know that you don't need one, in the case of
OpenID).

For OpenID-enabled patchwork instances, the registration link should
still be there, but could potentially direct to a login form, explaining
the use of OpenID.

Cheers,
