Removes weird exclusionary rule that makes many storage items and armors ethereal.

Currently anything with a storage value over 24 can't be hit and provides no protection value, rendering most of its attributes moot.

With this minor tweak, backpacks will provide a small measure of protection from harm at the cost of the risk of being damaged. All it takes is the removal of a small snippet of code.

This bit of code seems to me like something that's simply not been noticed until now, since things like purses and messenger bags run afoul of it already.
