Arasan 11.4

[jdart]

Arasan 11.4 is available from http://www.arasanchess.org.

Changes in Arasan 11.4:
1) Fix to KBP draw code.
2) Fix Winboard/xboard driver to send "O-O" not "o-o" for castling.
3) Fix time calculation in tournament mode.
4) Scoring changes, fixes for Rook mobility & rooks on open files.
5) Scoring change in king safety: don't count Bishops more highly
than Knights in evaluating king attacks.
6) The usual book fixes/additions.

I have also updated the Arasan test suite with 15 additional positions. Details at http://www.arasanchess.org/testsuite.shtml.
