Naz cdae2a978d Added ability to fetch collection posts by slug
closes https://github.com/TryGhost/Arch/issues/27

- We need a more convenient method of fetching posts belonging to a collection than by collection's "id". This change adds an alias to the existing endpoint `GET /collections/:id/posts/`. A non-valid ObjectID in the parameter is treated as a slug.
