Diagonal Win Checking Issue

[DrkWithT]

In the function below, I noticed that during test runs, the diagonal checks would lag behind by one placed piece. A diagonal of four will go unprocessed for a turn until the next move before being detected... This is likely because of a consecutive piece counting error in the diagonal checking helper function, specifically the while loop.
