Rook PSQT Tuned

This patch uses about half the changes of the SPSA tuning run:

About a month ago, xoto10's patch raised the mg value of the third rank
center files from -1 to 7 to encourage rook lifts to the third rank. About
three days later, Rocky's patch lowered this value from 7 to 3. This patch
raises that again from 3 to 12 and ends up greater than the original rook
lift patch.
