Table talk keeps its place in the chronicle

Live chat interleaved correctly, but a reload sank every past message
to the bottom: the rejoin sent the whole game history first and the
chat history after. Talk is now a tableTalk event in the room's event
stream at the moment it was said — the room file already preserved
the interleaving, since chat lines append between command lines — so
rejoining players read the banter between the battle lines where it
happened. The separate chatHistory message retires; unread counting
rides the event stream instead.
