Whether or not a pacifist can fire a gun is no longer based on the gun being harmful, but the chambered round being harmful (#36670)

fix: makes dragnet non harmful
tweak: pacifists can now use any disabler or stun setting on any energy gun
code: removed all of the pacifism check code from code/modules/mob/living/living.dm
code: gun objects no longer have a harmful variable, instead, ammo_casing objects now have a harmful variable, which is by default set to TRUE
code: if a pacifist fires a gun, it checks whether or not the round chambered is lethal, instead of whether or not the gun itself is lethal.
