Version 0.6

This update brings many technological improvements. Countless hours of debugging went into this :)

List of changes

Terrain has gone from being 64x64x64 to 192x192x192
The way that the system generates and stores chunks in memory has been completely changed:
- Chunks are now stored as sorted structs with a pointer to a blocks array that is allocated upon generation
- There are currently 27 of them in a 3x3x3 grid
- They are automatically sorted, and are looked up using a binary search algorithm
Debug screen has been redesigned, and shows more info
A special debug menu was added to options that provides a 3D xrayable map of the current chunk
Terrain generation is far more varied in terms of height
