Allow A/B testing

Hello!

I'm using your module since new version was introduced (before I used the 1x version). It works absolutemy wonderful!

I'd like to propose you to allow a/b testing with your module, or random choosing of ads.

I've tried to use the following code from Adsense Help center: http://adsense.blogspot.fr/2006/08/abcs-of-ab-testing.html

<script type="text/javascript">
    var random_number = Math.random();
    if (random_number < .5){
        //your first ad unit code goes here 
    } else { 
        //your second ad unit code goes here 
    } 
</script> 
<script type="text/javascript"     src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>

Even if Content Injector do use java script, it didn't allow me to use random script. I had to move back to AdSense code.

Please, consider allowing A/B testing in the module. Thanks.
