Description of change

Introduce --no-dom-globals CLI flag. With this flag set, following
globals won't be exported:

• setTimeout, clearTimeout, setInterval, clearInterval,
  setImmediate, clearImmediate
• console

These are provided by the DOM implementation in browser, so the
--no-dom-globals flag may be helpful when embedding node.js within
chromium/webkit.
