Add unique puzzle gimmicks for Bones, Shirts

[Poobslag]

Bones and Shirts don't have a unique puzzle gimmick like Skins does, and overall Merrymellow Marsh feels a little themeless as it doesn't introduce any major puzzle gimmicks.

Bones could have some kind of a "colorblindness gimmick" where all the pieces are the same color.

Shirts could have a "messing with the next queue" gimmick, which is something we wanted to experiment with.

Shirts could also have a "No Bag Randomizer" gimmick. We've never put this in the game, but it would be really crazy and force a completely different strategy.
