Players should each have their own mobcap

Currently, the mobcap for each player is around 70. This is fair, it makes surviving not too dangerous, and at the same time making farms is fine as well. But this changes when someone else logs on. This makes the mobcap 140. Now normally this wouldn't be a big problem right, but here's the thing. If one person's base is lit up, or someone's living area has a lot of spawnable spaces, that's a problem, because in the first scenario, where one player's base is lit up, means that they won't have many mobs around them, therefore not being able to take up much of the mobcap. This is troublesome for the other player, as they then get double the mobcap, meaning there will be 2x as many mobs. In the second scenario, where either a player is taking up a lot of the mobcap, mob farms have severely decreased efficiency, because mobs around player 1's base simply don't despawn fast enough for player 2's mob farm to function at its best. Having individual mobcaps for each player fixes all of this. Unless another player is around you, the mobcap is treated like singleplayer, and you won't have too many mobs, and mob farms should work properly too.
