NW.js + Svelte + webpack + nwjs-builder-phoenix

Svelte is modern JS UI framework, which runs at compile time, not in the browser. It generates JS.

• app - root directory for NW.js.
• app/index.html - default file (entry point) for NW.js.
• src - application sources.
• src/index.js - entry point of the app.
• src/scripts/prepare_dist.js - script to change field main in package.json in the build.
• npm start starts webpack-dev-server and NW.js with it.
• npm run webpack calls webpack which compiles all required JS-code (including node modules) to app/index.js and all required CSS to app/styles.css.
• npm run dist calls webpack and then makes the build to the directory dist.
