Cut down on some HP update spam

This increases the timer that mobs will send out updates
(It could probably be increased more)
This will also reset the timer every time SendHPUpdate is called
to prevent sending like 3+ completely useless updates at once
Also skip sending the update to the client if we're sending an
OP_Damage with the damage since the client will apply this number
