Add browserify config

[e-jigsaw]

Replace process.env.NODE_ENV by adding this config when using browserify.

React also written this config: https://github.com/facebook/react/blob/0ce28c6e88448af6eda69df66088b88e7248bbb7/packages/react/package.json#L29-L33

Thanks

Don't we also need to make it a dependency then?

[gaearon]

Also if we go with that, we need to add this to React Redux as well.

No, Just "browserify": "..."

Yes, I will send same PR to react-redux if this PR merged
