Fixed leaks, think about utilizing unlimited Z axis and high mobility of players

Fixed "chunk leaks", made a lot of bug fixes and optimization. Generated construction coming soon.

Also i think about utilize feature of unlimited Z-axis (in minecraft height limit approx 320 blocks ), probably generate something like huge mountains, or deep caves, or even planets, but
direction of gravity should be parallel to X/Y/Z.
Also, my project does not store generated chunks at all (but only changes made by players) it`s give a high mobility for players without issues, and i should utilize this feature too.
