auth/grant.go
Update error strings, add ErrNo*Store errors. Update error strings to consistently begin with a lowercase letter and end without punctuation, as per the Go style guide. See https://code.google.com/p/go-wiki/wiki/CodeReviewComments#Error_Strings For each type of Store, add an ErrNo*Store error (e.g., ErrNoTokenStore) variable, to prepare for our Context type, which will throw these errors when a Store is used without being set.
