King Psqt Tuning

Browse Source 
After a session of tuning for King Psqt I got some new values, which was later
tweaked manually by me Fauzi, to result in an Elo-gain patch which seems to scale
pretty well:

STC: LLR: -2.96 (-2.94,2.94) [0.00,4.00]
Total: 100653 W: 22550 L: 22314 D: 55789 [Yellow patch]

LTC: LLR: 2.96 (-2.94,2.94) [0.00,4.00]
Total: 147079 W: 25584 L: 24947 D: 96548 [Green Patch]

Bench: 4669050
