Rotation check schedule (Feature 20)

Register rotation_check: daily at review_time, claimed as
rotation_check:YYYY-MM-DD, it calls plan.MarkTried for yesterday.
MarkTried now emits rotation_review:{dinnerId}:{planDate} ("How was
{dinner}? Keep it in rotation?", URL /) for each Rotation check it
opens, in the same transaction. Nothing promotes a dinner to Regular.
