fix doomsayer once and for all

[sliverfishes]

Instead of just not giving value to playfields that have doomsayer, we should also heavily penalize any that play minions into a doomsayer board or damage it without killing it. These 2 things keep coming up, probably because of negative penalties ("bonuses") both in the code and in _combo.txt configs. Penalizing these boards should fix it once and for all. Do it in the behavior playfield value code still.
