Updated the textures for the following items:
Flower of Bygone World

Primal Stone

Added Nether Core, now used to upgrade armor at the forging table instead of being a crafting ingredient.
Changed the shader texture of the Sword of Cosmic Dominion to rainbow-colored rendering.

Added the ultimate weapon for this mod.
Optimized some code.
