Safe mouseflow script inclusion

mouseflow.js

  (function () {
    var msf_script = document.createElement('script');
    msf_script.type = 'text/javascript';
    msf_script.src =
            ('https:' == document.location.protocol ? 'https://' : 'http://') +
                    'cdn.mouseflow.com/projects/ba141427-dfd0-4d3a-acbe-37df41b6c8e0.js';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(msf_script, s);
  })();

(function () {
    var msf_script = document.createElement('script');
    msf_script.type = 'text/javascript';
    msf_script.src = '//cdn.mouseflow.com/projects/ba141427-dfd0-4d3a-acbe-37df41b6c8e0.js'; // http://paulirish.com/2010/the-protocol-relative-url/ (may cause issues with ie6 though)
    var s = document.getElementsByTagName('script')[0];
    s.insertBefore(msf_script, s); // why did you insert it on the parent node?
  })();

i dont think we should worry about IE6, it doesn't even show up in the stats anymore

well, it's more about who mouseflow is targeting. On some of our challenges we had a ton of IE6 users.

Officially we do not support ie6 at all, but technically we do make sure it is usable on ie6.
