Simple Stack: Stack any items to 64

Bug Fixes:

• Hoppers did not restack unstackable items
• Items did not properly shift click into crafting tables
• Fuel for furnaces did not automatically shift click into the correct place
• Shift clicking items into the player's inventory had different behavior from vanilla
• Crafting tables and anvils unstacked items when they were closed with items inside of them
• Items upgraded from the smithing table would disappear if shift clicked
• Items that were stacked in an anvil or smithing table would act odd and sometimes have bugs
• Enchantment table could enchant multiple items at once
