Massive reductions in unnecessary network traffic especially during high spam combat fights

- HP Updates now only send to others when HP percentage changes (0-100%)
		- HP Updates were sending excessively even during idle zones when HP wasn't changing at all
	- Attack animations now only send once per second versus up to a hundred times a second per Mob/Client
	- 17,000 OP_ClientUpdate packets per second have been observed in combat scenarios, some of the major culprits have been
		throttled without affecting what the client should see
	- Before and After packet differences under similar load/tests (Packets per second)
		- 7,000 - 8,000 	OP_Animation pps	After: 600-800 pps
		- 13,0000 - 17,000 	OP_MobHealth pps	After: 1-10 pps
		- 15,0000 - 20,000 	OP_ClientUpdate pps	After: 500-1,000 pps
	- Packet reports from a 46 client test here:

	- Servers who use Marquee HP updates will also recieve far less packet spam as they will only be sent when HP changes
