Patch v1.32

Fixes

Customers no longer lose their preferred weapon size and material class on being reloaded.
The Forgehammer and Tongs will no longer disappear if being held while dealing with a customer.
Customers spoken to while seated in the tavern will now stand up before moving to the smithy tent.
Weapon types now have a maximum swing speed to better balance the associated damage of lighter 2H weapons, and improve game feel.
Amethyst is now a material with price, attributes, and a spot in the ore stand. Some Amethyst nodes have been moved lower to enable mining.
Some gaps where tunnels joined caves in the mine, and where cave-ins have blocked outgoing tunnel entrances, have been closed.
