In the spirit of supporting JavaScript development for Atom packages,
this adds default support for es.next transpilation support in the way
that Atom already has default support for CoffeeScript transpilation.
There are many new features in ES6+ that make JavaScript development
easier and more enjoyable, particularly in terms of support for async code.
For reference, this was a much faster way to iterate on this than running `./script/build`
each time:
```
cp /Users/mbolin/src/atom/static/index.js /Applications/Atom.app/Contents/Resources/app/static/index.js
coffee --output /Applications/Atom.app/Contents/Resources/app/src --compile /Users/mbolin/src/atom/src/esnext.coffee
```
Run the following in the console to see how warm the cache was after startup:
```
global.require('../src/esnext/').getCacheHits()
global.require('../src/esnext/').getCacheMisses()
```
