title: jQuery JSONP ajax, authentication header not being set
body: <p>I'm trying to make an ajax request to the google contacts API with the following setup:</p>
  
  <pre><code>$.ajax({
    url: "https://www-opensocial.googleusercontent.com/api/people/@me/@all",
    dataType: 'jsonp',
    data: {
      alt: 'json-in-script'
    },
    headers: {
      'Authorization': 'Bearer ' + token
    },
    success: function(data, status) {
      return console.log("The returned data", data);
    }
  });
  </code></pre>
  
  <p>But the Authentication header doesn't seem to get set. Any ideas?</p>
