Add a trade history for each card.

Currently available metrics are "Price (USD/BCX)", "Quantity Sold (BCX)" and "Quantity Sold (BCX)".
They are good and give a big picture of the card value. However, they miss the market dynamics, especially on shorter timeframe.
It would be nice to have a trade history for each card, maybe the 10 or 20 last trades. This would greatly help identifying how market behave in relation to price changes of cards.
