[Hummingbird] Remove render-blocking JavaScript

Hi,
I did a Google PageSpeed Insights test and the desktop result was 91!

But unfortunately, the mobile one was only 65. The main culprit was all the hb.wpmucdn.com scripts were placed above the fold. How do I move them to below the fold?

You can see the results here:

Below are some of the above the fold javascripts and css files:
