v0.7 Alpha 4: World of Color

I figured if I was going to redo the textures from the World of Color update, I might as well steal the name while I'm at it.
I'm also two blocks away from being completely done with the 1.17 snapshot items, though that has probably changed by the time this release is out.

• Added Ancient Debris
• Added all the colors of Concrete (no powder yet, though)
• Added all the colors of Terracotta (no glazed terracotta yet, though)
• Retextured the Wool blocks and they look way better now
• Added Bone Block
• Added Chain, Impulse, and Repeating Command Blocks
• Added Dripstone Block
• Added Iron Trapdoor
• Added Lever
• Added Lightly Weathered, Semi-Weathered, and Weathered Copper Blocks (and waxed variants)
• Added Lightning Rod
• Added Oak Trapdoor
• Added Sea Lantern
• Rotated the Spyglass in the inventory (can't replace it with its old 2D texture without screwing it up outside of GUIs, unfortunately)
• Added Target
• Added Tripwire Hook
