show card with number as trump card and move name changing for double names to add player and out of constructor

tried to fix the overlap of round and predicted tricks. it seems like the problem is not the overlap of the text but that the panel is dynamocally resized after each card was played. i tried to fix it but didn't manage, good luck to anybody else who wants to try.
