Description

Instead of evaluating Google Analytics code right away, the official snippet allows asynchronous evaluation, if browser supports it:

<script type="text/javascript">
  // code stripped
  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();
</script>

Add new option 'async' to PAGE.includeJS.<array>

great, but as it seems to me, completely useless ATM if you use concatenation feature AFAICS.

and concatenation is also recommended by google.
just mention the latter to prevent anoying "concat-minify-compress" debate on principles.
