Preliminary testing indicates a great improvement of ~100 ELO
compared to previous versions. All test matches were bullet,
1 min no increment. The games were played _without_ arbitration,
so all games where played out to their end. This was to verify that
engines could actually perform a checkmate when given the chance.
Will add more games for future revisions,but this seems quite
clearly to be a positive change. Strangely, on of the version
v1.7.0, v1.8.2 or v1.9.0 crashed after 100 or so rounds. Could be
a random thing, but should update chester package to handle this
with more information in the future.
Hard to tell exactly which part caused the increase, since this PR
contains quite a few bugfixes pluss changes. In any case, nice to see
that the now less buggy version plays better!
