Updated apigility-utils.min.js

- To include Hyperagent 0.3.0, which fixes an issue with how headers were merged
  into the ajax implementation, and thus allows passing versioned mediatypes for
  the Accept and Content-Type header, as well as passing the authorization
  header.
Merge branch 'hotfix/hyperagent-0.3.0'

Update to hyperagent 0.3.0
