Remove diagonal lines from the win check

On the shipped starting board, Green occupies the main diagonal and Violet occupies the anti-diagonal. These two entries therefore make both sides already satisfy hasLine(); after any legal first Green move, Green's diagonal is broken while Violet's remains, so checkWinner() declares "Violet wins" before the AI takes a turn. Dao's four-in-a-row win is horizontal/vertical rather than diagonal (GamesCrafters), so these diagonals need to be excluded or the initial layout changed.
