I initially sort the moves by simply calling Quiesce() after making each
root move, and using this score to sort the moves the first pass.  This
will basically sort them into descending order based on the static evaluation
except for those moves that are captures or are affected by captures.  Once
the first iteration is done, I use node counts from then on.
