Update 0.2.6 - OGS Updates, Single Player Undo

[Hart Laboratories]

Got up to speed with some more background OGS changes that happened today.

Also there is a bunch of the code related to OGS which I was working on going live that should fix a bunch of edge cases problems. Lucky it doesn't seem like people have had any issues as nobody has mentioned them but they were little time-bombs.

The most noticeable change will be that games vs the computer AI now have an undo option. This will revert the game to let you take your last move over.
