title: js warning: Resource interpreted as Script but transferred with MIME type text/plain
body: <p>i´m firing an ajax/jsonp request to my cloudant app: </p>
  
  <pre><code>    var obj = $.ajax({
          url: "http://xyz",
          dataType: 'jsonp',
          success: function(data) {  
              //SOME CODE  
          },
          error: function() {
              //SOME CODE
          }
      });
  </code></pre>
  
  <p>the response is ok and i can read out my data. 
  but I´m getting the following js warning: </p>
  
  <pre><code>Resource interpreted as Script but transferred with MIME type text/plain.
  </code></pre>
  
  <p>i need to make this request an jsonp request (cross domain policy), AFAIK jsonp returns as a script and gets executed by the
  browser. 
  do i have to set a request header? 
  I tried it with the 'accepts' and 'converters' options, but didn't make it work yet.
  (I´m using GoogleChrome, but also happens in Safari/FF)</p>
  
  <p>cheers, 
  tom</p>
  
  <p>PS: I want to get rid of the warning as this ajax request gets triggered every 2 seconds. So the console looks pretty bad...</p>
