Check client's allowed grant types for authorize requests #111

Add checks for restricted grant type to Authorize Controller.
Means that clients need 'implicit' grant type to use implicit flow, and
clients that can't use auth code flow get bumped on the authorization step
not the token step.

Make more sense to have checkRestrictedGrantType in ClientInterface instead
of ClientCredentialsInterface as its not really anything to do with
'credentials'.
