title: JSON.stringify escapes double quotes every time when stringified
body: <p>I am storing JSON objects retreived from web service to objects in javascript. In many places this gets stringified(This obj goes through some plugins and it strigifies and stores it and retreives it) and it adds multiple slashes. How can I avoid it ?</p>
  
  <p><a href="http://jsfiddle.net/MJDYv/2/" rel="noreferrer">http://jsfiddle.net/MJDYv/2/</a></p>
  
  <pre><code>var obj = {"a":"b", "c":["1", "2", "3"]};
  var s = "";
  console.log(obj);
  s = JSON.stringify(obj);
  alert(s); // Proper String
  s = JSON.stringify(s);
  alert(s); // Extra slash added, Quotes are escaped
  s = JSON.stringify(s);
  alert(s); // Again quotes escaped or slash escaped but one more slash gets added
  var obj2 = JSON.parse(s);
  console.log(obj2); // Still a String with one less slash, not a JSON object !
  </code></pre>
  
  <p>So when parsing this multiple string I end up with a string again. And when tried to access like an object it crashes.</p>
  
  <p>I tried to remove slash by using <code>replace(/\\/g,"")</code> but I end with this : <code>""{"a":"b","c":["1","2","3"]}""</code></p>
