v.0.10.0:
Improvements
Better repetition detection. Compared to the previous version, the engine will convert more winning positions and less often run into threefold repetitions.
Evaluate passed pawns based on their squares (instead of just counting them)
Evaluate pieces and passed pawns based on their rank and file distances to the kings (and replaced the old evaluation terms which only considered the total distance to the kings)
The tuner is now faster, uses less memory and it's less cumbersome to add new evaluation terms.
