LogicSummoner::tick guards the whole hand-refill block on the first vint

sent zero, so the hand we dealt was the only one the player ever got.
named after what it is and set to four.
12951 is SendBattleEventMessage, the in-battle emotes and quick chat. it
carries a LogicBattleEvent: a type byte, the sender account and three
int lists - ticks, coordinate pairs and params. it decodes now instead
of being dropped with a warning. the client renders its own emote
locally, so nothing is echoed back yet; the relay belongs with a real
opponent.
