Add experimental contempt factor This is very crude and very basic: simply in case of a draw for repetition or 50 moves rule return a negative score instead of zero according to the contempt factor (in centipawns). If contempt is positive engine will try to avoid draws (to use with weaker opponents), if negative engine will try to draw. If zero (default) there are no changes. No functional change.
