Support ES6 export declarations about react-docgen

@fkling Is this something that's already underway? I can lend a hand if needed, this would be huge for me.

[fkling]

I haven't started yet. If you want to take a stab on it, I'd appreciate it!

[banderson]

Ok, great, I'll see what I can do.

For those who need this ASAP and want a clue of where to start, I spiked out the minimal functionality I needed here. This just covers allowing ES6 style imports and default exports. Hopefully I can eventually flesh out the remaining details and get it merged in here.

@banderson: Did you make any progress with this? What's the status?

[banderson]

@fkling I got React.createClass recognition for ES6 default exports and ID'ing React in ES6 import statements in just that small change linked above. This works well for my use cases. Now I'm working on PropTypes recognition for using named imports (e.g. import React, {PropTypes} from 'React';) and in restructured assignment (let {PropTypes} = React;).

Before this is done, we'd need to ensure all import export cases are covered, and tests for all the existing cases :/ Glad to help out as much as I can, would welcome help from anyone else that knows more use cases if they exist :)

[fkling]

Great, thanks! Feel free to make a PR for the things that are working. The destructuring assignment case should already be covered with 2539959.

This should work as of 623c192, release with v1.3.0
