Snaglist 0.4.0

Added

• Show as a QR code. With GitHub set up, What is sent offers the same pre-filled new issue as a QR code,
  for a phone to open when the computer is not online, such as one being set up. It comes first when the
  computer looks offline, with the reason above the privacy statement. A long report goes in shorter: first
  without its technical details, then with the words cut to fit, and the view says what the code holds. The
  link is shown as text with Copy the link, and Download keeps the whole report. The code is dark on
  light in every theme, with a text description, and works from the keyboard. The encoder is part of
  snaglist.js, so there is still one file and no libraries. Leave it out with send: { qr: false }.
  Send a report with a QR code has the steps.
• The help centre on the web, at https://themightytrex.github.io/snaglist/help/, with search, a menu of every
  article and display settings.
• A changelog, in CHANGELOG.md, listing every version since 0.1.0.

Security

• The QR code holds only what the preview shows. Nothing typed into the page, and no email address or key,
  reaches the code (test SEC-20). The QR tests, QR-01 to QR-05, check the encoder against the design system's
  own and the view in every theme.
