Exposes _data/team.yml as publicly accessible JSON
Jsonifies
Does it the jsonify way
More flexible method of generating json files

Previous solutions have created json by using a page template. That's fine
but actually generates an html file with json in the body. In addition to
sending the data with the wrong content-type it also is rendered as html by
browsers, javascript, etc., and would have required more maintenance for
new data sets.

This commit exposes an endpoint at `/api/<data>.json` for every dataset in
the _data directory. For example, this site will have _data/team.yml
exposed at `/api/team.json`
Prevents json files from being cleaned by jekyll
Merge branch 'team-members-api' of github.com:18F/18f.gsa.gov into team-members-api
