Allow json files in _data dir

[benbalter]

Per @holic's excellent comment over in github/pages-gem#64 (comment), any valid JSON with a .yaml extension in the _data directory is valid YAML and can be read it. Tested locally, and it appears to be true.

This pull request simply expands the allowed file extensions to be read in from yml and yaml to also include json.

What happens if members.json and members.yaml exist?

Good point. @benbalter Could you please add a test for this?

Is it also worth mentioning in the docs that JSON is valid frontmatter? How about _config.json?

I don't think that JSON is valid frontmatter is it? Sure, the YAML parser
will parse it, but does it create something useful for frontmatter?

Not particularly useful (YAML is easier to read/maintain), but AFAIK this:

---
layout: post
title: Some post title
---

is equivalent to this:

---
{
  "layout": "post",
  "title": "Some post title"
}
---
