-fix for issue 604 (Land play limitation should not apply in all cases)
-- this adds a "castMehod" variable to MTGCardInstance. IF this variable is 0, the card was not "cast" (or for lands, "put into play" as part of the lands rule), but "added" to the battlefield with some other effect. On the other hand, if this variable is set, it means the card was cast 
-- as we discussed, I did not touch the "alternateCostPaid" variable, as I'm still not really sure these two concepts are actually the same
