Use MobComparator automatically if viewport exceeds 255 players

[lare96]

If the viewport exceeds 255 players, the MobComparator should be used automatically (instead of having it as a toggleable setting). The viewing distance should also be cut (need to decide by how much)

View distance should be dynamic, incrementing by 1 tile every tick until you've maxed out your viewport or there are 255 entities in view. Reset on teleport, relog, etc

@ryleykimmel doesn't that mean it'll take 6 ticks just to show an entity 6 squares away for example? at least when you initially enter a new region?
