Modules and NPM2

[arunoda]

@mnmtanish I just implemented NPM2 support for storybooks.
See: #356

It'll work with current modules.
But I want to know about how it will work with custom modules (user supplied modules.)

Could you possible to do some review on this.

If there's an issue, we could alias core module repos with require.resolve

We can try a few open source repos with customised storybook and see whether it works with npm2. We can try repos with custom .babelrc files and webpack config files. If you know any, I can check them out.

I think this is working pretty greatly.
