Add a "already bought" section

With it, when looking at a lego piece, we could have :
"buy", "comes in", "colors", "edit", "sell", "wishlist", "collection", "price history", "description" AND "already bought"
with informations like how much were already bought, when, and which store from

A Purchase History for each item, that seems nice.
