/* 	Ping Update except better:
	We call this once per second and check for people's pings. If their ping happens to be too high, we increment some timer and kick them out.

	Why do we do that? Well, I'm a person with unfortunately sometimes unstable internet and happen to keep getting kicked very unconveniently for very short high spikes. (700+ ms)
	Because my spikes are so high, the average ping is exponentially higher too (700s really add up...!) which leads me to getting kicked for a short burst of spiking.
	With this change here, this doesn't happen anymore as it checks if my ping has been CONSISTENTLY bad for long enough before killing me.
