Delay Load

Adjust script embeds to lazy load.  Does not work with all scripts.

OLD:
<script type="text/javascript" language="javascript" src="//c.amazon-adsystem.com/aax2/getads.js"></script>
<script type="text/javascript" language="javascript">
  //<![CDATA[
    aax_getad_mpb({
      "slot_uuid":"1b1938e7-10cd-4599-8147-f917bd87f463"
    });
  //]]>
</script>

NEW:
<script>
setTimeout(function(){
  var s = document.createElement('script');
  s.setAttribute('type', 'text/javascript');
  s.setAttribute('src', '//c.amazon-adsystem.com/aax2/getads.js');
  s.onreadystatechange = function() {
    if (this.readyState == 'complete' || this.readyState == 'loaded') {
      aax_getad_mpb({
        "slot_uuid":"1b1938e7-10cd-4599-8147-f917bd87f463"
      });
    }
  };
},5000);
</script>
