+  *Deals damage back to the hulk's arm.
+  *
+  *When a hulk manages to break a wall using their hulk smash, this deals back damage to the arm used.
+  *This is in its own proc just to be easily overridden by other wall types. Default allows for three
+  *smashed walls per arm. Also, we use CANT_WOUND here because wounds are random. Wounds are applied
+  *by hulk code based on arm damage and checked when we call break_an_arm().
+  *Arguments:
+  **arg1 is the arm to deal damage to.
+  **arg2 is the hulk
