cards: rename class "Card" to "SimCard"

There are the classes IsimCard and UsimCard, which inheret from Card,
which is the base class for a normal non ISIM/USIM simcard. Card also
has methods in it that are related to simcards, so it is not just any
"Card", it is a SimCard and should be called that way.
