Feature Request: Accept greedy moves less easily

[Pbatch]

Greedy moves (the current most likely move) are annoying if they accepted too easily. This is because they:

• Pollute PGNs for broadcasting
• Disable the ability to play a live game
• Add confusion to the text debugging

It would be better to wait a set amount of time (I.e. 300 ms) or a certain number of frames before accepting a greedy move.
