[Suggestion] Show an alert if the item you're trading is different from the one you whispered

In order to reduce the amount of players that get scammed (especially new players), it would be nice to have an outline colorful border on the item in the trade window.

Similar to the outline you already see when you receive a whisper about an item in your stash, that item will have a purple outline to make it easier to find it in the stash.

The outline could also appear in the trade window, so the player purchasing it can be sure that the item in the windows is the same (id) as the one they clicked on the trade website.

If the item is not of the same id, then the outline could be red.

This could even go further and show a confirmation box when the trade is being done and the item is not the same, to make the buyer double check before actually confirming the trade.

We just need instant buyout as Jonathan has promised to avoid all this nonsense.
