Convert killers to a vector
...
Add infrastructure to threat killer moves as a vector,
this will allow us to easily parametrize the number of
killer moves, instead of hardcode this value to two as is now.
This patch just add the infrastructure, no functional
change.

Refine "few moves" in "last minute surprise"
...
It seems that "few moves" works because we extend the good
captures at the last ply of PV, so code it directly.
This version seems defenitly stronger then previous one.

Restore original movepick modulo space inflation

We have a regression somewhere here so restart from zero
and proceed one change at a time.
With this modification we have the same strenght of
"Introduce Stockfish" patch that is our strongest to date.
