title: How to get Magnific Popup working with Browserify
body: <p>I'm trying to get Magnific Popup to work alongside Browserify and I can't seem to get it to work. I don't have an in depth knowledge of the Browserify setup. 
  All I keep getting is the following error:</p>
  
  <pre><code>Uncaught TypeError: cache.$btn_enlarge.magnificPopup is not a function
  </code></pre>
  
  <p>Any help would be gratefully received! </p>
  
  <p>Thanks, 
  Tom</p>
