Commit ID 3913726d1c8ef3b994dd8090c98814fa7e7f5874

Use single value for KingProtector. After some recent big tuning session, the values for King Protector were simplified to only be used on minor pieces. This patch tries to further simplify by just using a single value, since current S(6,5) and S(5,6) are close to each other. The value S(6,6) ended up passing, although S(5,5) was also tried and failed STC.
