Subject: [PATCH] Build React in production mode by default

https://facebook.github.io/react/downloads.html says:
"By default, React will be in development mode. To use React in production mode, set the environment variable NODE_ENV to production (using envify or webpack's DefinePlugin). A minifier that performs dead-code elimination such as UglifyJS is recommended to completely remove the extra code present in development mode."
