Use StoryQuerySet methods
Use StoryQuerySet methods

When possible, use custom methods on StoryQuerySet to deal with
connected stories.

In the future, it might be possible to get rid of some of the methods
I put on story instances for dealing with featured stories now that the
query API is cleaner, but leave it in place for now.
