UIFramework v1.5.0

Added

• A timed action on a random time and after chat lines. Streamer.bot's timer dialog offers a fixed interval, a
  random one and "only after so many chat lines", but code can set only the interval. UiTimer in the host block
  keeps the other two: Sync brings the timed action in line with the settings (a running timer keeps its
  countdown unless the schedule was just saved), Rearm draws a random timer's next wait each time it fires, and
  NoteLine / TakeLines count chat lines per platform and hold a start back until there are enough. See A timed
  action in docs/Schema.md.
• Five convention keys for it: autoStartEnabled, autoStartIntervalMinutes, autoStartRandom,
  autoStartIntervalMaxMinutes and autoStartMinChatLines, with page, row, labels and help in English, German and
  Spanish. A game declares them with key and default alone.

Changed

• Trivia and Hangman run their automatic rounds on it (Trivia v9.3.0, Hangman v13.3.0). The host copies of
  Trivia, Hangman, Blackjack and Battleship are the games' current ones.
