Title: Added support email for Vkontakte.

Recently API Vkontakte began to support email. See https://vk.com/dev/auth_sites.
> Quote: Also API server returns the user `email` if your application has Web-site type, appropriate permissions has been requested, the user has an email address and gave access to it.

Is returned by the method `getExtraParams()`.
