#145 "Flipped" state similar to "tapped" state

[ashsaver]

There was a set of cards that "flipped" when a condition was met and had a different set of properties when flipped (eg Jushi Apprentice/Tomoya the Revealer)

It's technically implementable without code changes, but the picture would stay the same. Because flipping also changes the card orientation, it would be implemented similar to the tap function.
