v6.0

Changed signature of OCG_DuelSetResponse, now it's OCG_DuelSetResponse(OCG_Duel duel, const void* buffer, uint32_t length)
Pass OCG_CardData* as second parameter of OCG_DataReaderDone
Updated MSG_SWAP_GRAVE_DECK and made it no longer dependent on the client by passing the count of cards to be moved from the graveyard, and an array of bits to tell the client which cards should go in the extra deck
