Do less futility pruning for captures.

The idea of this patch is that if capture can be described as
"less valuable piece takes more valuable piece" it's not really correct
to add only piece value of captured piece to static evaluation
since there can be more threats in other places and opponent can't really
do much but recapture our capturing piece which leaves us space for
more captures thus winning more material and increasing static eval.

Introduce bonus for queen infiltration

Idea is that queen feels much better when it can't be kicked away now
or later by pawn moves, especially in endgame. Special thanks to
Linmiao Xu for the original idea of this patch.
