Stack to Nearby Chests

Added support for Traveler's Backpack mod

• Removed the "Quick Stack" and "Restock" buttons from backpack screens, as they already provide equivalent functionality
  • Key bindings still work

Fixed a bug where disabling the "Show buttons on the Creative inventory screen" setting would also hide the buttons in Survival mode

The "Red Background" favorite indicator style no longer covers the item

Added all Copper Chest variants to the default "Stacking Targets" and "Restocking Sources" lists

The "Stacking Targets" and "Restocking Sources" lists are now sorted alphabetically
