Webpack optimizations (#140)

* Less repetition in webpack configs. Minify CSS classnames in production.

* Ignore all optional deps of moment.js. Fixes #138

* Added target to webpack config

* Automatically extract all 3rd party modules into a separate 'vendor' chunk

* Inline only assets that are smaller than 10KB

* Added autoprefixer options

* Replaced sinfle babel transforms with the stage-1 preset. Cleaned up webpack configs.

* Do not include hot module replacement in production
