how to help with ES6 features

[Paulo Lopes]

Hi,

For Vert.x javascript support I've prototyped the Promise API as per:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise
http://www.ecma-international.org/ecma-262/6.0/#sec-promise-objects

I see that it is not in the complete list, If someone would "mentor" me
with how to get it in nashorn, I'd gladly contribute the code.

As an example here's some demo:

https://gist.github.com/pmlopes/3d86f67943b3ffd9dd9aff73067de0a2

And it has been tested to work with babel.js to allow transpiling `async`
`await` to Promise API.

Cheers,
Paulo
