Refactoring for deployment

Renamed view field in routes to “name” to match scratch-www, not using “view” field because all scratchJr views are name/name.jsx

renamed server to dev-server, and app.js to index.js for consistency with www, and to make clear it’s only the way it runs in development.

Added html-webpack-plugin

dev-server/handler.js
