Simplify some kingring penalties expressions The new "weak" expression helps simplify the safe check calculations for rooks or minors, (but the end result for all the safe checks is the exactly the same as in current master) The only functional change is for the "outer king ring" (for example, squares f3 g3 h3 when white king is on g1). In current master, there was a 191 penalty if any of these was not defended at all. With this pr, there is this 191 penalty if any of these is not defended at all or is only defended by a white queen.
