React.Node utility type is "unknown"

React.Node utility type added in flow 0.53 is "unknown"

Example code:

import * as React from 'react';

type Props = {
  content: React.Node,
};

class MyComponent extends React.Component<Props> {
  render() {
    return <div>{this.props.content}</div>;
  }
}

export default MyComponent;

react-docgen (3.0.0-beta7) output:

{
  "description": "",
  "methods": [],
  "props": {
    "content": {
      "flowType": {
        "name": "unknown"
      },
      "required": true,
      "description": ""
    }
  }
}

It looks like we don't support any of the React.* types. We probably have to special case them (cc @danez).

What else do we need to support besides React.Node ?

I added a PR for this, it was fairly easy to add.
