Fix for using require.js in chrome plugin

gistfile1.js

require.attach = function (url, context, moduleName, onScriptLoad, type, fetchOnlyFunction) {
  var xhr;
  onScriptLoad = onScriptLoad || function () {
    context.completeLoad(moduleName);
  };
  xhr = new XMLHttpRequest();
  xhr.open("GET", url, true);
  xhr.onreadystatechange = function (e) {
    if (xhr.readyState === 4 && xhr.status === 200) {
      eval(xhr.responseText);
      onScriptLoad();
    }
  };
  xhr.send(null);
};
