#145: Fix Auth_OpenID_SuccessResponse

In 263a6c7, @liayn made
Auth_OpenID_ConsumerResponse::identity_url and
Auth_OpenID_ConsumerResponse::endpoint private, then redeclared them
as public in subclass Auth_OpenID_SuccessResponse, breaking
functionality such as calling
Auth_OpenID_ConsumerResponse::getDisplayIdentifier() on instances of
Auth_OpenID_SuccessResponse. To fix that, I made the properties on
Auth_OpenID_ConsumerResponse public as they were before and removed the
redeclarations in Auth_OpenID_SuccessResponse.
