title: Don't encode urls in querystring stringify
body: <p>Is there any option for <code>qs.stringify</code> that will <strong>not</strong> encode the urls?</p>
  
  <pre><code>$ node
  &gt; var qs = require("querystring");
  undefined
  &gt; qs.stringify({"url": "http://domain.com"});
  'url=http%3A%2F%2Fdomain.com'
  </code></pre>
  
  <p>I want the folowing output:</p>
  
  <pre><code>'url=http://domain.com'
  </code></pre>
