Add move log file

[PraxTube]

Would be very useful to have a log file (or at least a log print output) at the end of the run. For instance, a log.txt file that has all the moves that were made in the run. You could even copy these moves and paste them into chess.com.

This shouldn't be too hard to implement, just have a list that gets updated whenever a move was made and write these changed to a file (you don't even need a list really).
