Title: massive amount of changes to scope handling 

1. Ensures client scopes are always validated
2. ensures client grant types are always validated
3. moves client scope storage to OAuth2\Storage\ClientInterface
4. refactors storage class to interface change
5. TokenController now requires OAuth2\Storage\ClientInterface

This breaks backwards compatibility, but offers significant security fixes. Please review.
