Allows multiple qualities of the same item to occupy one stack.

Stack Quality is safe to add any time, but if you want to remove the mod make sure you split up any stacked items or they may get compressed into a single quality item when you reload the game without the mod.

It is currently in beta so there is likely to be bugginess and incompatibilities.

I'll fix any issues as they get reported and will remove the beta tag once I believe most issues have been resolved.
