Rematches, seats that travel by phrase, the keeper's bell with the hour where they live, the host's leave for the gallery to talk, and seats doubted before they are dropped

Ported from Wiz-War, where each earned its keep. All on the ledger:
galleryTalk, challenge and rematch lines, gallery chat signed with a
name, held seats on a rematch table's room line. Twenty-two protocol
checks against a scratch server and a replay after restart.
