Modules, async/await and other modern JS

[justinfagnani]

First, this is a great library! - it's the best organized and documented highlighter in JS I've found.

I've been in need of a pure JS modules highlighter, so I forked Rainbow and ported it to modules here: https://github.com/justinfagnani/rainbow

Along the way I did some other changes, like replacing callbacks with async/await and how the module script is created. Next up is getting the tests passing and a build setup for the worker.

Would you be interested in having these changes upstream? Most of them are breaking changes - even just getting modules wired up idiomatically means dropping the global Rainbow - so it'd have to be a 3.0.

Thanks for the great project!
