joakin e6081106f1 Use EcmaScript modules instead of common.js modules
Why: Because they are the approved standard by TC39 and Ecma for
JavaScript modules.

Changes:
  * Wrap mw-node-qunit in run.js to register babel to transpile modules
    for node v6
  * Change all sources in src/ to use ES modules
    * Change constants.js to be able to run without
      jQuery.bracketedDevicePixelRatio given ES modules are hoisted to
      the top by spec so we can't patch globals before importing it
  * Change all tests in tests/node-qunit/ to use ES modules
  * Drop usage of mock-require given ES modules are easy to stub with
    sinon

Additional changes:
  * Rename tests/node-qunit/renderer.js to renderer.test.js to follow
    the convention of all the other files
  * Make npm run test:node run only .test.js test files so that it
    doesn't run the stubs.js or run.js file.
