v0.0.1-alpha.17

For the operator: no migrations and no new settings; the image replaces
alpha.16 as it is.

Added

• The site has an icon in the browser's tab and on a phone's home screen:
  the bot's globe drawn flat, with the pin large enough to read at 16 px.
  The privacy page has it too, and /favicon.ico answers.

Changed

• A Telegram player's photo is shown wherever their name is: the day's
  table and the world's in the Mini App, the site's result, the days page,
  the leaderboards and the mini profile, to anyone, not only inside a group
  both are in. A player who hid themselves stays "Anonymous" with a plain
  face, and before the chat's reveal the other rows still have neither name
  nor photo.
• Your own face is your Telegram photo: the profile button in the header,
  your profile and your rows, in the Mini App and on the site signed in
  with Telegram. It is asked of Telegram when the app opens, at most once a
  day, so a new photo shows the next day.
• Photos stay current: a page shows the kept ones at once and asks
  Telegram in the background for the ones missing or a day old. Names were
  already read from Telegram on every visit.

Fixed

• A double tap on the panorama zooms on a phone. The phone's browser sends
  a mousedown of its own after the tap, and the panorama stopped the zoom
  it had just started on it, at once or after a few degrees. A double click
  with a mouse always worked.
