Allow customizing of scope validation per user #86
Description
The Situation
I want to be able to only allow some scopes to be used by specific users.
The Problem
As far as I can see digging through the code, you can't customize validation for scopes, or token creation (aside from actual generation).
Current Solution
Right now the only solution I see is doing it on the controller level, but that seems messy and possibly has some ways around.
