More precise checks evaluation in king danger Remove overlapping safe checks from kingdanger: - rook and queen checks from the same square: rook check is preferred - bishop and queen checks form the same square: queen check is preferred Increase bishop and rook check values as a compensation.

Right now count of this squares does not really matter. - maybe some small extra bonus can be given for overlapping checks. - some ideas about using popcount() on safechecks can be retried. - tune this safecheck values since they were more or less randomly handcrafted in this patch.
