No Last Hit Sound

This should eliminate the last hit sound that plays when you kill an enemy if you want/need to do that for any reason.

Do remember that this gets rid of that sound completely; if anything else uses that sound, they will be silent too.
Also, since the sound confirms that you actually killed an enemy, you'll get less feedback in combat. However, if you're looking for more immersion, then that's probably a plus for you.
