Sol stone has negative volume, causes crash when splitting

[Coolthulhu]

Splitting expects positive volume, but sol stone is made of obsidian, which has positive density, so its negative weight means negative volume. Attempting to split a sol stone or the negative volume obsidian stone created from it will crash the game.

Ha! Apt, but the crash is unintended. Another good experiment, thanks @Coolthulhu

Items with negative weight/volume should, when you attempt to dismantle them, be removed with a message: "%s disappears in a puff of logic." :)

Incidentally, it seems the code does not crash, but rather aborts when the game checks whether crafting didn't result in more material than it started with. When you split the -1000g sol stone into eg. 3 pieces, you get 3x -333g due to rounding, which is technically more than you started with...
