T_Damage

targ		entity that is being damaged
inflictor	entity that is causing the damage
attacker	entity that caused the inflictor to damage targ
	example: targ=monster, inflictor=rocket, attacker=player

dir			direction of the attack for knockback
point		point at which the damage is being inflicted, used for headshots
damage		amount of damage being inflicted
knockback	force to be applied against targ as a result of the damage

inflictor, attacker, dir, and point can be NULL for environmental effects

dflags		these flags are used to control how T_Damage works
	DAMAGE_RADIUS			damage was indirect (from a nearby explosion)
	DAMAGE_NO_ARMOR			armor does not protect from this damage
	DAMAGE_NO_KNOCKBACK		do not affect velocity, just view angles
	DAMAGE_NO_PROTECTION	kills godmode, armor, everything
