Introducing a new puzzle and a few small fixes

The most annoyingly fiddly puzzle in the game is gone! The tilting table puzzle in the Human Sacrifice exhibit has been replaced with a nicer water-based puzzle. It's a better fit for the atmosphere of the exhibit.

The solution to the drawer puzzle in the Black Death exhibit has been adjusted to make more sense. This was a frustrating puzzle for a lot of people, not because it was too difficult, but because the solution wasn't logical. It's better now.

Additional changes:

• Fixed music volume failing to decrease during puzzles

• Added an option to mute music entirely during puzzles (Settings / Extras)

• Replaced the Black Death exhibit music with something less jovial

As always, thank you for being a part of this weird little game. Stay safe and healthy out there.
