Improve handling of queen imbalance
We double the bonus for potential threats by minors and rooks against
our queen, in case of "queen vs pieces imbalance". Hopefully this will
improve a little bit the evaluation for this well-known Stockfish weakness.

Remove late irreversible move extension
We simplify away the late irreversible move extension, which
does not seem to be necessary in the current master.

Remove conditional_more_than_two().
This is a functional simplification that removes the conditional_more_than_two()
function, which was quite strange and kooky. Note the very minor change to the bench
value.
