Fix SurfaceBlock/GroundBlock not generating when StoneBlock has a value above 127

- Also removed prefixes from the logger messages. While it may look nice
on servers with only TC installed, it looks strange on production

which also have other plugins that don't align their messages. Maybe it
can come back as a setting?
Smooth radius for each biome. Need help with settings comment.
Fix SurfaceBlock/GroundBlock not being able to have values above 127

The byte read/write methods were removed so that Java falls back on the
integer read/write methods, which shouldn't change 172 (hardened clay)
to -82.

Also added a cool comment there.

but this would break existing configs.
