Version 0.85.0

NMTS can now see how the week's free-trial places are being taken, without storing anything about who took them.

The free trial gives out a fixed number of places each week, first come first served, one per account. Somebody making accounts in bulk from one internet connection could take the whole week without anything noticing, and NMTS has been counting places per connection since 0.69.0 — but that count is held in memory only and is lost on every deploy, so the record said a connection went past its share and never how far. There is now an operator-only reading of the day so far, which answers with counts of counts — how many connections took one place, how many took two — and never with anything that points at a connection. It stores nothing, so a deploy still ends the day’s count, and nothing about it refuses anybody.
