docs: Initializes Parse Facebook integration.  Call this function after you
  have loaded the Facebook Javascript SDK with the same parameters
  as you would pass to<code>
  <a href=
  "https://developers.facebook.com/docs/reference/javascript/FB.init/">
  FB.init()</a></code>.  Parse.FacebookUtils will invoke FB.init() for you
  with these arguments.
  
  @param {Object} options Facebook options argument as described here:
  <a href=
  "https://developers.facebook.com/docs/reference/javascript/FB.init/">
  FB.init()</a>. The status flag will be coerced to 'false' because it
  interferes with Parse Facebook integration. Call FB.getLoginStatus()
  explicitly if this behavior is required by your application.
