Update to Normalize.css 1.1.2
Update to jQuery 1.10.0
Update to jQuery 1.10.1
Update to Google Universal Analytics

This is an optimized version of the official Google Universal Analytics snippet,
based on http://mathiasbynens.be/notes/async-analytics-snippet.
The only difference is that this version still uses
`document.getElementsByTagName('script')[0]` instead of `document.scripts[0]`
for Firefox < 9 support.

Unminified, optimized code:

    (function(window, document, script, variableName, scriptElement, firstScript) {
      window['GoogleAnalyticsObject'] = variableName;
      window[variableName] || (window[variableName] = function() {
        (window[variableName].q = window[variableName].q || []).push(arguments)
      });
      window[variableName].l = +new Date;
      scriptElement = document.createElement(script);
      firstScript = document.getElementsByTagName(script)[0];
      scriptElement.src = '//www.google-analytics.com/analytics.js';
      firstScript.parentNode.insertBefore(scriptElement, firstScript)
    }(window, document, 'script', 'ga'));

    ga('create', 'UA-XXXX-Y');
    ga('send', 'pageview');

Minified:

    (function(b,o,i,l,e,r){b.GoogleAnalyticsObject=l;b[l]||(b[l]=function(){(b[l].q=b[l].q||[]).push(arguments)});b[l].l=+new Date;e=o.createElement(i);r=o.getElementsByTagName(i)[0];e.src='//www.google-analytics.com/analytics.js';r.parentNode.insertBefore(e,r)}(window,document,'script','ga'));ga('create','UA-XXXX-Y');ga('send','pageview');

Closes #1347 and #1369.
