Pregeneration System
The new pre-generation system now uses a spiraling system in order for regeneration to get progressively better as time passes; instead of a full generation being necessary to feel the effects.

Not only that, but it now uses a better system for detecting already existent chunks; so it will go blazingly fast over chunks that have been already generated.


Bug Fixes
Fixed an issue where paper detection wasn't done properly, basically rendering all paper-only features broken.
