Introduced scopes. Created a Scope type and a scopeStore interface, along with the memstore methods for the scopeStore. This will allow applications to define access with granularity, so users can grant access to some data, not _all_ data. We're operating on the assumption that there won't be an unreasonable number of scopes defined, so there is no paging operation included for the ListScopes method. This is a decision that may have to be revisited in the future, depending on usecases.
