Back in Classic

Full Changelog: https://github.com/SaishoVibes/Back-in-Classic/compare/v0.8.0-alpha.2...v0.8.0-alpha.3

Fixed Reach-Around (Bug id 18) Added creepers_explode_death gamerule (automatically false, but will be set to true) to control the creepers exploding after death as that can be too annoying. Updated all biomes to properly spawn the correct mobs in correct amounts. Added Dirt and Sod Slabs (Dirt and Grass Block Slabs) to recall to the original dirt slabs being in game. Sod Slabs are only the colour of Alpha Foliage, so use them to brighten up your builds!
