title: Saving parameters with dat.gui seems broken?
body: <p>There seems to be a problem with saving parameters in dat.gui, or I'm missing something really obvious..</p>
  
  <p>The problem shows when clicking the gear icon which should open a popup with the JSON to be saved. Also saving to local storage does not work for me. Here are two JSFiddles:</p>
  
  <ul>
  <li><p><a href="http://jsfiddle.net/navFooh/XZcde/" rel="noreferrer">http://jsfiddle.net/navFooh/XZcde/</a> with dat.gui.min.js, clicking the gear throws an error in the console: <code>Uncaught TypeError: Cannot read property 'forEach' of undefined dat.gui.min.js:3</code></p></li>
  <li><p><a href="http://jsfiddle.net/navFooh/8Hek6/" rel="noreferrer">http://jsfiddle.net/navFooh/8Hek6/</a> with dat.gui.js, clicking the gear icon does show the popup with JSON, but the parameter <code>x</code> does not show</p></li>
  </ul>
  
  <p>The sample they have online works fine (see comment for link). But they have minimized all their sample code, including the lib itself. So I can't even resolve if they're even using the latest build.</p>
  
  <p>Any help would be greatly appreciated.</p>
