Set limited game mode, AI changes, primitives and _cards.dat corrections

New set limited ,where you get a deck two random sets.

Still playing with the AI values and hueristics.

Cards fixes. Masters Edition should be named ME1 and the Mythic Edition is MED, the cards multiverse ids are still the same so the decks and references should not change.
