One of the things that I modified was the default transposition table
size.  I don't know how this affects performance or strength, but in
the default configuration it was using 9 Mb of physical memory per
instance (WebChess runs many instances).  I cut it down to only a few
Mb by reducing the ttblsz value in ttable.h (via the Makefile).
