Patch Notes: Smoother sign-in at midnight

Fixed

Signing in, and joining the world, failed for many players for an hour or two after midnight UTC every night. The game no longer has every player's client check in with the server in the same second when the day changes. Each client now waits a random 0–10 minutes past midnight.
For those few minutes after midnight, the ground's gathering nodes, your profession's day and the town reports stay on the day before's until your client catches up. Nothing is lost.

DAY-TURN: spread each client's UTC day change over 10 minutes (the nightly sign-in failures) by @Lattymoy in #1119
