Title: Just add singleton to description of authorize_resource

Inside controller I don't use load_resource and just write authorize_resource. But this controller declared as resource in routing file and I was a bit confused when I was trying to understand why a nil comes to can rule in abilities. And it was because I had missed :singleton => true for authorize_resource.
