UltimateSpawn

Changelog:

• Updated the whole mod logic, now it should work much better and stable than 1.x versions. This should resolve most, if not all, issues regarding lags or unknown behaviour of finding safe spot for players.
• Fixed wrong configuration ranges not allowing users to set negative coordinates values, fixes #1
• As of 2.0, modpack developers may adjust lower-upper values of the 'y' coordinates from -2048 to 2048, technically fixes #3
• Fixed a bunch of typos in the configuration comments
• Heavily reworked and optimized the safe spot finding algorithm, fixes #5, #6 and possibly #2.
• Improved code readability a bit.

ALWAYS do backups, here may be dragons after all.

As of this version, 1.16.5, 1.18.2, 1.19.x are deprecated. They will receive only critical bugfixes. As of this version, 1.20.1 is considered to be a LTS version. 1.21.1+ builds will come up a bit later.
