v0.6.0

Changed

• The About page describes the project instead of showing placeholder text: the current version, the experiments, the stack with major versions read from package.json, credits, source and licence.
• /home is a landing page with a short introduction, Get started and About buttons, a card for each experiment and the current version, instead of placeholder text.
• The Help page explains how to get around the app, run it locally, use the npm commands, add pages and state, and cut a release, instead of showing placeholder text.
