Improve sets handling

Move the “check unknown sets” method inside the cards database, so that
it can be executed when the card database gets reloaded after a card
database update.
Additionally, show the user a welcome message the first time they run a
new cockatrice version, so that they know why they get shown the “edit
sets” window and how to hide/disable sets.
