Remove and replace DoubledIsolated penalty by Doubled
The values for both penalties were very close, so DoubledIsolated can be removed and replaced by Doubled.

Queen Mobility Tweak
It's ok to have low mobility values for the Queen in the middlegame, but it's absolutely not ok to have low mobility values for the Queen in the endgame.
Decrease penalty for bad mobility in MG and increase it in EG.
