Auth token and avatarUrl security improvements (#1514)

* Remove AbstractOAuth2Controller

There is no reason to provide an implementation for a specific oAuth2
library in core; it's not generic enough (eg. auth-twitter can't use it).

This code could be moved into another package which auth extensions
depend on, but it's a negligible amount of relatively simple code that
I don't think it's worth the trouble.

* Introduce login providers

Users can have many login providers (a combination of a provider name
and an identifier for that user, eg. their Facebook ID).

After retrieving user data from a provider (eg. Facebook), you pass the
login provider details into the Auth\ResponseFactory. If an associated
user is found, a response that logs them in will be returned. If not, a
registration token will be created so the user can proceed to sign up.
Once the token is fulfilled, the login provider will be associated with
the user.
