Documentation for 1.0.0: README, guides, screenshots, GitHub files

- README: what Control4Free is and why it reaches menus and sign-in, features,
  a quick start, screenshots, requirements, limitations, credits.
- docs/: installation, playing, troubleshooting (every message the page and the
  app can show), how it works, and the WebSocket protocol.
- CONTRIBUTING.md: building, testing, code style, releasing.
- Screenshots of the page on phones and a PC and of the app, made against the
  real service built for the host, at the example address 192.168.1.20.
- Issue forms, a contact list pointing at the guides and private security
  reporting, and FUNDING.yml.
- CHANGELOG.md dated. CI now publishes this version's section of it as the
  release notes rather than the whole file.
- THIRD_PARTY.md: the DualShock 4 diagram the buttons are drawn after (CC BY
  3.0), and Apollo Save Tool for the package settings.
- Page: the Vibration setting no longer promises to buzz when a game rumbles,
  which 1.0.0 cannot do yet.
