Streaks now roll over at the member's local midnight (their timezone) instead of UTC. This stops streaks from resetting for members who visit late at night. Daylight saving time is handled, and it falls back to the board timezone when a member hasn't set their own.
The flame "active" window is more tolerant of timezone offsets, so a valid streak is no longer hidden by mistake.
Changes
Renamed the "Total daily visits" stat to "Total days visited" for clarity (it is the lifetime count of days a member has visited, not a per-day number).
