This subgen creates a new Webpack config environment by - creating conf/webpack/<EnvName>.js - creating src/config/<env_name>.js - requiring and exporting the new env in conf/webpack/index.js The commit introduces a basic config template that is supposed to be populated by the generator's users. Various more fine grained subgen options can be added at a later time (e.g. prompting the user if new run scripts should be added to package.json). The subgen's basic functionality is backed up by unit tests that check - if files are created - if conf/webpack/index.js contains correct import/export
