Arasan 11.3

[jdart]

Arasan 11.3 is available from http://www.arasanchess.org.

This is the same version that played in the recent CCT11 tourney, plus a few last minute book fixes.

Changes in Arasan 11.3:
1) Fix bug that caused occasional early search termination.
2) Fix Winboard communication to use a thread for greater reliability.
3) Keep game file open - fixes some occasional failures to save games.
4) Fix Makefile to build "pgn2book" utility (some code fixes in this too).
5) Some search changes: Lessen futility margin. Enable additional extensions at ply 0. Enable a version of razoring.
6) Improved move ordering based on node counts.
7) Bug fix in outpost scoring.
8) Passed pawn scores increased.
9) Bug fix in GUI: bad PV display at high search depths.
10) Larger opening book.
