Working of Auction Validation
-------------------
1. Business Functionality
-------------------------
This is a script, which renders the winners of each auction items, after the auction ends. After that, the winner users are allowed to purchase the items.
If an item is a show-window element - it means that cannot be purchased by users - it can be set on the item during the creation,
by default the items has this parameter true.

2. Technical Description
-------------------------
Dynamic parameters:
-During the item creation, these value (bot_need_win [tiny integer]) can be set by the administrator on each item.
-If the auction ends, and the item has this parameter true, this validation script stick a bot bid in, between the last user bid and the auction end datetime,
so the user will lose the auction. By default, the new bot bid has the creation date one second before of the item auction end datetime.
