Feature: change card count

[LuckyTurtleDev]

A option to change the count of the cards, which will be selected.

At the most games, I have played, multiple players had often bought large number of all the same cards. Because of this 2 pile of cards was extremely fast empty. At the same time only a small number of other card was bought. A large number of cards would give the player a large selection, so they would not buy all the same cards.
