Proof feed: one message per purchase, and it says InstantAdPay

Marty, reading the feed on 25 September: "I see the level 1 payout, I see
a level 2 payout, but I don't see who purchased something and what they
bought." And in the main Crypto Team Build group the same lines carried no
product name at all, so nobody knew what they were from.

feedgroup.js composes one message from every event of a purchase
transaction: the buyer and the package on top, the level payouts under it
with their dollar equivalents, then who was passed over and why. It is
triggered on AdminPaid, the last event the contract emits for a purchase,
which is how the missed-payout notice already knows the whole transaction
is indexed. Tier payouts and purchases are no longer posted one line at a
time. In payouts mode a purchase that paid no member (root or unsponsored
buyer) stays silent, as before. Every post now opens with the InstantAdPay
header in the main group as well as the payments topic.

Composed against three real transactions from the live index before
shipping: three tiers, a double pass-up, and a root purchase. QA member
walk: 0 bugs.
