Can now get all highscore entries grouped by shared highscore dates.
This gives a complete list of all the lotteries and their winners.
- By-date takes a epoch date to match a given lottery.
- By-name uses query parameter `name` for searching for all winnings by
name.
- Both /by-date and /by-name don't just return the wine _id, but
resolves it's wine reference.
