fixes for https://github.com/yiisoft/yii2/issues/951#issuecomment-25934549

just a type correction and suggestion on adding a comma and one word (ie 'by') to make it more easily to be understand.

Re-implemented RBAC by following more closely to the original NIST RBAC model. Dropped `yii\rbac\PhpManager`.
