INSANE optimization 2

Now I added the usage of the C# Job system, BurstCompiler and made the code similar to ECS. I also added some more optimization to the scripts and now playing on 1 thousand particles on 24FPS on my laptop is a normal thing. Also I forgot to set the quality of the gravity scripts to normal, they're on ultra settings by default now. And yes 1k particles 24FPS on ultra settings... I don't even know what to say...
