More space for codes

MSG_DECK_TOP, MSG_TAG_SWAP and MSG_DRAW will now send the card position after the code, instead of setting the last bit if the card is faceup.
MSG_SELECT_BATTLECMD and MSG_SELECT_IDLECMD wil now send the operation type of the effects that can be activated after the description of the effect, instead of setting that as the last bit of the code.
MSG_SELECT_CHAIN will now send the chain count after the hints, and the effect type will be sent after the effect description, instead of before the owner's code.
