Player: real zero gravity

A mod that adds a realistic zero-gravity simulation.

Players can move freely in 3D space, build up momentum, push off blocks, and control their orientation without being constrained to world axes.

The mod includes configurable push reach and a simple API for integration with other mods.

This mod is primarily intended as a library for space-engine mod and other mods and has limited functionality on its own. However, you can test it using the command /spaceGravity <mode> <player>, where <mode> is either 0 or 1.
