Add tie mechanism when position repeats itself 3 times.

[marcel-valdez]

Description
The problem/use-case it solves
There are times when the best move is to avoid losing so a given position can repeat itself infinitely when both parties make the best move.

The solution from the user's perspective
This is a draw, the board should detect this and declare the game a draw.

• Effort: S+
• Value: Medium to low
• Ambiguity: Low

Design & Implementation Suggestions

• We can store the board hash in an array and use that to determine if a repeated pattern of hash has occurred.
