Arasan 13.2

[jdart]

Arasan 13.2 is available from http://www.arasanchess.org.

Changes in Arasan 13.2:
1) Fix in search to eliminate some unnecessary re-searches.
2) Fixes to material scoring for unbalanced material positions.
3) Simplified bonus code for Bishop in endgames with pawns on both sides.
4) Revised bonus for trading material when ahead.
5) Misc. scoring fixes, esp. for connected rook on 7th.
6) Utility programs such as makebook now do not create a log file.
7) Another/better fix for UCI output after a quick mate.

For the first time, a pre-built Intel Mac binary is available.

I ran a 400 1:0 game test match on Linux against 13.1, both engines with 2 cores, ponder on, and 13.2 scored +150 -114 =136 (54.5%) or about +30 ELO. Your mileage may vary.
