omniscient in web worker thread

[Gozala]

This (at least until react adds support for web workers) will depends on #49. I have in the past successfully used vtree + vdom in the web worker thread in prototype that completely followed Elm-html and it's todo-mvc implementation. You can see it running all of the app code in web worker in action and an implementation that depends on bindings for vtree + vdom .

As with #49 I'd be willing to give this a shot, as long as project owners will be onboard with this.
