Parallelism - Pulsing entities and players in parallel divide and conquer manner. #1007

Utilizes CPU resources better. I tested this using artificial load inside GlowEntity.pulse() method - each pulse every entity generates 10000 random integers. Here are my benchmarks (CPU: Ryzen 2600X): A message is shown every 120 ticks inside each world thread.

Possible concerns: I know in the future AI for mobs will be added and right now I don't know for sure if it will affect it. What I did is just speed up iteration inside the GlowWorld.pulse() method.
