React-Redux Support

[sangwonl]

While I've been working on supporting react-redux into extension-boilerplate, found a interesting project from react-chrome-redux. It looks very reasonable for extension architecture with react-redux.

So, I forked extension-boilerplate and put react-redux related things with react-chrome-redux and minor changes such like lint. If you're interesting of them, please check on https://github.com/sangwonl/extension-boilerplate-react-redux
