Update react-docgen version

Hi! Thank you for awesome styleguide.

I'm using the Intersection types of flowtype.
At that time the following errors occurred.

ERROR in ./~/react-styleguidist/loaders/props.loader.js!./src/js/components/ui/IconButton/IconButton.js

Errors in the react-docgen is looks like this is the cause.
However, in the latest version of the react-docgen since corrected that you want to update.

By the way, now we have to avoid to specify as follows the latest version of the react-docgen.

// styleguide.config.js
module.exports = {
  // ...
  propsParser(filePath, source) {
    return require("react-docgen").parse(source);
  }
}

Thanks! Unfortunately can’t make release now because I have some unfinished stuff in master (I know I shouldn’t do this $-) I’m going to release 4.0.0-beta next week. Sorry for inconvenience.

Thank you for quick reply & merge! Loocking forward to next week's release 😄
I'm rooting for development of styleguidist.

Hi, I get a similar error, when I try to use an stateless component which is decorated with "react-css-modules". Error: No suitable component definition found.

import React, {PropTypes} from 'react';
import CSSModules from 'react-css-modules';

import styles from './label.css';

const propTypes = {
    content: PropTypes.string
};

const Label = ({content}) => <label styleName="label">
    {content}
</label>;

Label.propTypes = propTypes;
export default CSSModules(Label, styles);
