primitivus card_game: bug fix and improvement - changeset 56f8a9c99194 introduced a bug because it connected all the list widgets to the parameter change callback. This is not OK because the Tarot is using a list form that is not a parameter. - some list processing was raising an error when the data is not initialized - display the "choose contrat" dialog with valign='top' to allow the user see his hand while taking the decision.
