webpack.config.js

/*
 * Webpack (JavaScriptServices) with a few changes & updates
 * - This is to keep us inline with JSServices, and help those using that template to add things from this one
 *
 * Things updated or changed:
 * module -> rules []
 *    .ts$ test : Added 'angular2-router-loader' for lazy-loading in development
 *    added ...sharedModuleRules (for scss & font-awesome loaders)
