title: jquery.d.ts errors when added to projects
body: <ol>
  <li>I created a new TypeScript project.</li>
  <li>Created a folder called types</li>
  <li>Downloaded jquery.d.ts from <a href="https://github.com/borisyankov/DefinitelyTyped/tree/master/jquery" rel="nofollow">https://github.com/borisyankov/DefinitelyTyped/tree/master/jquery</a> and placed it in the folder. </li>
  </ol>
  
  <p>If I create a new TypeScript file and drag jquery.d.ts onto the document, such that the only thing at the top of the page is. </p>
  
  <pre><code>/// &lt;reference path="types/jquery.d.ts" /&gt;
  </code></pre>
  
  <p>I get 101 Errors. Starting from the top of jquery.d.ts - VS has a problem with boolean in the async?: boolean; line. </p>
  
  <pre><code>interface JQueryAjaxSettings {
  accepts?: any;
  async?: boolean; 
  </code></pre>
  
  <p>What am I doing wrong here, I'm assuming that jquery.d.ts has some form of dependency, but I don't know where to start?</p>
