Create more detailed answer sets for the hint round

[jayolee]

Currently, I created two answer sets for each category. These answers are used when there's a hint. But because there're only two sets, sometimes it doesn't make sense. For example, if a hint is "it's an object," an automated player might say "strawberry" as an answer.
Not urgent, just better for improving UX.
