Live chat replay

Chat replay is on by default for archived streams, and it turns a long recording into something closer to the live experience, with messages, Super Chats and moderator activity appearing at the timestamps where they happened. One thing catches creators out repeatedly: trimming or editing the archive in Studio's editor strips chat replay for good. If the stream had a dead patch you wanted to cut, you are choosing between a tighter video and keeping the chat that came with it. Polls also fail to appear in replay, so anything decided by a poll wants saying out loud on camera.
