Rules into Voltorb Flip

[FL-]

Added rules into this minigame, copied from HeartGold/SoulSilver, but using the standard choice menu rather than a custom one. For the last group, due to different controls (no touch screen and you can only mark as voltorb, rather than voltorb and numbers) I changed

pbMessage(_INTL("Select \"Open Memo\" to mark the cards."))
pbMessage(_INTL("You can mark the cards with the numbers 1 through 3, but also with a Voltorb mark."))
pbMessage(_INTL("When you have an idea of the numbers hidden on the back of the cards, touch \"Open Memo\" and select the cards to mark."))
pbMessage(_INTL("If you want to remove a mark, touch the mark again, and it will disappear.")

To:

pbMessage(_INTL("Use action button to mark the cards."))
pbMessage(_INTL("When you have an idea of the Voltorb or number 1 hidden on the back of the cards, mark the cards."))
pbMessage(_INTL("If you want to remove a mark, select the mark again, and it will disappear."))

The only lacking text are the ones from top screen (some short lines), since I don't know a better place to put it.
