Highlight JS with Turbolinks

The Turbolinks gem doesn't let you use the $(document).ready() calls that highlight_js requires to highlight your code. Instead include the following at the bottom of your application.js:

$(document).on('page:change',  function() {
  $('pre code').each(function(i, e) {hljs.highlightBlock(e)});
});
$(document).on('page:restore', function() {
  $('pre code').each(function(i, e) {hljs.highlightBlock(e)});
});

This runs the text highlighting when the page is changed or restored using Turbolinks.
