More chat icons; message menu inside the bubble

- 18 more icons (gamepad, computer, food, ...) with a test that keeps the
  server whitelist and the client picker identical.
- The ⋯ menu of a message moves into the bubble foot (next to the time); its
  popup opens upwards inside the bubble and is limited to the bubble's width.
