title: Webpack will not resolve JQuery-UI Definitions
body: <p>I have the following code in my TS file...</p>
  
  <pre><code>require("jquery-ui/ui/widgets/datepicker.js");
  require("angular-ui-date/dist/date.js");
  </code></pre>
  
  <p>When I run the code I get the following error...</p>
  
  <blockquote>
    <p>Module not found: Error: Cannot resolve module 'jquery-ui/datepicker' in //code/my-app/node_modules/angular-ui-date/dist
     @ ./~/angular-ui-date/dist/date.js 3:66-97</p>
  </blockquote>
  
  <p>So I ran <code>tsd install jqueryui --save</code> and then added the following to the same file as the require...</p>
  
  <pre><code>/// &lt;reference path="../../../typings/jqueryui/jqueryui.d.ts" /&gt;
  </code></pre>
  
  <p>based on <code>src/main/typescripts</code> but I still get the same warning when running webpack</p>
