Removed DamageSoundType and replaced it with a string "tag" instead to allow mod creators to create custom damage sounds

Fixed damagemodifier sounds being completely ignored due to a variable misname
Added structure damage possibility for melee weapons so you can break down windows with a crowbar in spectacular fashion (it's clearly a very inferior method to plasma cutters though)
Clown hitsounds are in now which is awesome. Beat up some clowns!
