There's always one more bug...

In 1.37 the bishops' king attack code could infinite loop in some rare cases. That's been fixed now.

Also, I made a little change to passed pawn bonuses...
And, the search is about 3% faster due to a change to hashing of qsearch nodes. That's a massive improvement of maybe 1 elo.

Actually, the change to hashing may prove more helpful than 1 elo because the hash table is no longer getting flooded with so many (almost worthless) zero depth entries.

Thanks to all the testers!! Sorry for the bug!!
