Improve external package support

I wanted to include angular 2 project, but didn't find any way of doing it

For many external libraries, you can just <script src> it in the HTML and it will work. For example, here's a wich that uses three.js.

The big missing piece there is @types support, of course. I'd like to address that somehow, probably by just preloading a bunch of common libraries for now.

Ideally, I'd like it to be possible to just do

import * as THREE from 'threejs';

and have it Just Work, pinning the current version, loading @types, and loading runtime code from a CDN. That will require some thought and work though.

As for Angular, which is what you specifically mentioned, that will probably require some special treatment to get compilation to consume your source + Angular in the same compilation. I need to look into it; I haven't done very much with Angular > 1 yet. It's on my todo list, though.

I'd love to use this with @types support and create react/redux component examples. The libraries I'd need preloaded are react, react-redux, and redux
