Conflicts:
code/game/objects/items/weapons/stunbaton.dm
Made all obj/item/weapons have "swing_hit" as their default hitsound.
Made hitsound not play when the attack misses.
Adds agonyforce var to stun batons, which causes halloss and eye blur.
Also did some clean up of stun batons, and fixed the stun baton's bcell
var being of type weapon/cell/high instead of weapon/cell.
