build(webpack): update webpack packages

Update webpack and related packages to the latest 3.x versions. This
prevents errors from node-gyp when attempting to build fsevents (OSX),
which is an indirect dependency of webpack-dev-server (via chokidir)

See https://github.com/strongloop/fsevents/releases/tag/v1.1.0
