Title: Hardwire multi_json backend

The `multi_json` gem dynamically selects a JSON implementation from a list of
candidates. Since we cannot control which gems are installed on a user's
machine, this patch hardwires `multi_json` to use the included copy of `ok_json`.

`ok_json` is a pure-Ruby JSON encoder/decoder that is bundled with
`multi_json`. `ok_json` may not be as fast as other choices, but speed is not
critical for our application.
