title: jQuery not being found by icheck using webpack (Angular 2)
body: <p>I am writing an app using Angular 2, webpack and I am using the icheck front-end library (<a href="http://icheck.fronteed.com/" rel="nofollow">http://icheck.fronteed.com/</a>) which requires jQuery.</p>
  
  <p>I am requiring them in my component thusly:</p>
  
  <pre><code>var jQuery: any = require("jquery");
  require('../../../js/jquery.icheck.min.js');
  require('../../../css/checkbox/orange.css');
  </code></pre>
  
  <p>This build successfully using the webpack server and npm, but I get an error in the browser:</p>
  
  <pre><code>Uncaught ReferenceError: jQuery is not defined (jquery.min.icheck.js:11)
  </code></pre>
  
  <p>I have used this plugin before in an Angular 2 component but I never had any problems like this. I have compared the current app with the working app and I can't see any differences; it should work!</p>
  
  <p>I am really up against it now and have to get this prepared for Monday. Anyone have any problems like this?</p>
