Copper Overhaul

• Increased overall performance.

• Decreased file size from 1.78MB to 848kB.

• Now copper conduits don't need to be full 3x3 towers. Now you can travel through two parallel copper columns.

• Copper conduits now need to be at least 2 blocks high to be able to travel through them.

• Walking a coppered lodestone block will automatically magnetize you (if you are wearing metallic armor).

• Doors and trapdoors can now be locked. (Doors work the same way as double chests)

• Added two new gamerules which are experimental and should not be changed. (magnetizeNonMetallic and enableHorizontalMagneticTravel)

More changes on magnetic travel are coming soon (Including horizontal traveling!)
