Had a little bit of time, added a feature that changes the border colour when it is that players turn.

I think we are using a fair bit of CPU when just idling in the game. Because both threads are checking to see if its their turn constantly. It we did something like with 3P05 assignment 3 where the thread goes into a waiting state, using a monitor, until notified it would use less CPU. Something to think about, I don't think I personally will attempt it though.
Fixed compile error.
