refresh tokens: store and validate scopes. 

A refresh request must fail if it asks for scopes that were not
originally granted when the refresh token was obtained.

This Commit:

* changes repo to store scopes with tokens
* changes repo interface signatures so that scopes can be stored and
  verified
* updates dependent code to pass along scopes
