Roll up contents of child route folders as arrays rather than objects (or have an option)

[allthesignals]

Jekyll has a concept of posts which are treated as a general iterable collection of items rather than properties of an object. It would be nice to have an option to have these items rolled up as an array, which seems more of a restful approach (intuitively, this is how I expect to use something named posts).

So this:

├─┬ cms
  ├─┬ posts
  | ├── my-post.yaml
  | └── another-post.yaml

Becomes this:

{ cms:
{ 
  posts: [
      { title: 'post-1' },
      { title: 'post-2' },
  ]
}
 }

I'd be interested in your thoughts on this.

@allthesignals interesting, will have a look into this.
