Copper and Caverns
Adds copper (replaces stone tools) to slightly slow down game progression, and makes the underground more dangerous.

About this Mod
Stone tools are replaced with copper tools, slowing down early-game progression and requiring you to hold onto wooden tools for a bit longer. This also means "stone" (now copper) and iron have been pushed further underground, making them more of a challenge to get and making each tool stage more rewarding.
Beneath the surface is a thin crust of vanilla underground generation with coal and copper ore. Beneath that is a large, dangerous cavern with iron, diamonds, and other valuables.
Cherry trees spawn in forest biomes.
I made this mod because 1) I don't like stripmining and 2) I don't like how in the first 5 minutes of the game, you can immediately jump right from wood to stone to iron tools without even going underground.
