Title: Provide best possible email address

Per the OmniAuth wiki:

`email` - The e-mail of the authenticating user. Should be provided if at all possible (but some sites such as Twitter do not provide this information)

Since the email is definitely available, it should be provided. Defaults to preferred (which is optional), but will fallback to the account email (which is always available).
