[Completed] enhance Shop to obey Item amount conservation.


There are two ideas in the shop docs
- The functionality can be changed so that the are not duplicated and therefore sets a limit on the number of items that can be bought.
- You could also make it dynamic in the sense that you could buy back items that you just sold.

Both of them are quite common requirements for a Shop solution.
Could you please add them as built-in feature?

These already exist with the "ShopAddRemoveBinding" component. It is explained in the feature scene. I'll update the documentation asap
