Sound when you shoot to player

NAPOMENA: Kome treba nesto prevesti od ovoga teksta neka kaze!
At lessons (at polish lesson) I got idea to do this.
This will play sound(beep) to you when you shoot to another player

Also added support for callback OnPlayerLoseHealth and if you uncomment rest of OnPlayerUpdate you can use OnPlayerGainHealth and OnPlayerHealthChange

Just simple and easy.
