Add ES6 modules

[prettydiff]

Please add ES6 modules. I am sure support is likely red across the board, but it would be handy to spell that out as a major missing feature is the browsers.

X-Ref: compat-table/compat-table#316

Seems like they haven't been fully shipped in any browser:

Modules are "medium" on our (Edge’s) priority list. So, we've not started development, but development is likely some time in future.

This is now underway for Edge: https://dev.windows.com/en-us/microsoft-edge/platform/status/moduleses6

I believe modules are already in V8, but hidden behind a flag until address resolution can be standardized. https://github.com/nodejs/node-v0.x-archive/wiki/ES6-%28a.k.a.-Harmony%29-Features-Implemented-in-V8-and-Available-in-Node
