Hand the sponsor to PolHunter, and put its payouts in the P&L

PolHunter now pays a bounty when a hunter brings someone who turns up and
hunts, and the person who gets it has to be the one that member actually
joined under here. The sign-in payload carries sponsorRef and the join date
across so PolHunter is never guessing from a cookie.

Its payouts are real POL from its own faucet and none of it passes through the
ad contract, so the P&L could not derive it. It now reads the figures across,
cached and fail-soft, and shows finds, bounties and matches as their own card.
