[MERGED PR] Nadir increase to max players allowed (60 > 70)

[Zamujasa]

The biggest reasons I think it's a bad idea to make it the same pop level is that on Oshan and other maps, a breach isn't a huge issue. It's bad, and will get people killed, but vacuum is survivable for a long while, everyone spawns with small air tanks, and suffocation damage goes away once you get to a safe place.

Acid is much nastier, and can leave entire rooms basically off-limits until someone well-equipped enough can fix it. Walking into the acid deals a bunch of damage and disfigures your face. More people also means more bystanders and rubberneckers that make fixing problems harder.

Higher population means more chaos, and Nadir is _really_ sensitive to chaos.

I don't have any real opinions on the merge. But it is worth considering the ramifications of more people beyond just how cramped it is.
