Decrement uniqueness counter when items are destroyed.

[murphy-slaw]

Is your feature request related to a problem? Please describe. I would like to use this for my pack for rare artifacts, etc. As it stands, once an item's uniqueness count is exhausted, then it can never be crafted or looted again, even if every existing instance of the item is destroyed (by lava, the void, etc.)

Describe the feature you'd like It would be nice if items could decrement their uniqueness counter when they are removed from the game, possibly as a configurable option per item type.
