title: PhantomJS isn't saving cookies
body: <p>I'm running the latest version of PhantomJS on Windows 8.1. Here's my code:</p>
  
  <pre><code>console.log('cookies: ',phantom.cookies);
  
  phantom.addCookie({
      domain:'google.com',
      path:'/',
      expires:(new Date()).getTime() + (1000 * 60 * 60),
      name:'test',
      value:'value'
  });
  
  phantom.exit();
  </code></pre>
  
  <p>And I tried calling it like this:</p>
  
  <pre><code>phantomjs test.js --cookies-file=cookies.txt
  </code></pre>
  
  <p>and</p>
  
  <pre><code>phantomjs test.js --cookies-file="C:\path\cookies.txt"
  </code></pre>
  
  <p>Either way, <code>cookies.txt</code> isn't being created and <code>phantom.cookies</code> is empty. How do I make PhantomJS save cookies?</p>
