Originally, the drawscore implementation #1066 was intended for both contempt/humbleness and Armageddon support. Since then it turned out however that
the parametrization doesn't even span all possible combinations
the effect on opening selection etc is very miniscule
we were using symmetric settings between white and black anyway
As we have a working contempt implementation now with #1791, we can reduce drawscore to the one remaining use case, where Armageddon is one extreme case, and we only need 1 parameter for that instead of 4.
