Support CSSModules for SASS.

[stereobooster]

I need this feature to have out of the box integration with react-toolbox. See react-toolbox/react-toolbox-example#35

The question is if we have:

REACT_APP_SASS=true
REACT_APP_CSS_MODULES=true

Does it always mean we want CSSModules for SASS? I suppose yes

+1 to this, I just ran into this and was thinking about possibly contributing code but I'm not the world's best CSS Modules expert... perhaps I'll look at it tonight.

Solution is simple, question is how to integrate it

  'SASS': {
    toArray: 'loaders',
    getDev: function () {
      return {
        test: /(\.scss|\.sass)$/,
        loader: "style!css?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!postcss"
      }
    },
    getProd: function () {
      return {
        test: /(\.scss|\.sass)$/,
        loader: ExtractTextPlugin.extract('style', 'css?modules&-autoprefixer&importLoaders=1!postcss')
      }
    }
  },

@stereobooster - Does that seem to work?
