timeout add custard - write these files to the document if conditions for extra custard are met

mustardcustard.js

        // Mustard Cutting
        if ('querySelector' in document && 'addEventListener' in window) {

            // add class to HTML tag
            (function(H){H.className=H.className.replace(/\bno-js\b/,'js')})(document.documentElement);

            // add custard if screen size is big enough
            var windowWidth = document.body.clientWidth;
            if(windowWidth > 768){

                // load scripts - from cdn but with a fallback if we can't connect
                document.write(unescape("%3Cscript src='https://cdnjs.cloudflare.com/ajax/libs/gsap/1.19.0/TweenMax.min.js' type='text/javascript'%3E%3C/script%3E"));

These are meant to be written before the closing </body> tag. This is so that we can load larger filed from a CDN but provide a fallback if necessary. Also, if the screen is a small size, we disable some of the fancier javascript that's better displayed on desktops.
