Slower practice games, and custom practice matches

[pressgoal]

For testing purposes to see what kind of mistakes my bot is making, I think it would be useful to have the option to tell the game when to do the next turn. It would also help if we could set up custom boards for our bots to play on. If there is already a way of doing this, I apologize and would appreciate being told how.

Ok, while not a great solution. I did find the .txt file with all of the practice game fen strings just located in the resources folder, so you can edit that if you'd like. From what I can see, you'd have to make some pretty major changes to the ChallengeController.cs script to add telling the bots when to move, and I don't feel like doing that. If anyone has already set that up though, I'd love to see it.
