Fixes

• HMR is now longer enabled for simple compilations. You can now compile development builds that won't constantly ping a non-existent dev server.
• react-transform-hmr now only runs when HMR is enabled.

Improvements

• Unit tests now only run in watch mode when explicitly requested. This makes it much more convenient to run tests on any environment without having to struggle with the singleRun flag in Karma.
• There is now only a single webpack configuration (rather than one for the client and one for the server). As a result, configuration has once again been split into a base configuration which is then extended based on the current NODE_ENV.

Deprecations

• Removed Koa server (sad days).
