Settings UI & new Gamerule

• Now you can set gamerules easily with a interface! Type the command: /function forgecraft_lpmc2:settings to start the menu.
• New Gamerule: IsTextureEquipment. Just like IsTextureArmor, it determine if forging set the item model texture. You cannot reverse this action for the items that are already applied.

( Don't mind the extra resource pack file. Currently the Modrinth upload system is bugged)
