The following improvements have been made:
1. Auto232 master mode now functions fully.
2. External program auto232 to ICC now functions correctly.
3. There is now a 'dumbing-down' level setting to weaken CSTal2 for the
benefit of weaker players. Level 50 is the strongest (full play strength), 1
the weakest.
4. The verbosity of CSTal2 may be reduced. In this case it won't greet an
opponent at the start of a match and thank him at the end. If the computer
is playing or the book information or best-line information is available,
then, in keeping with our honest-play policy, the opponent will still be
alerted.
5. Several chess engine stabilisations and improvements have been made.
