GNU Go 3.1.19 released January 2, 2002

This is a bugfix release. There's not many changes since 3.1.18
but one important one, the patch gunnar_1_19.1. Without this
patch, GNU Go 3.1.18 was prone to crashes, probably crashing
more than once per 100 games.

Patches in this release:

gunnar_1_19.3. Bugfix in aftermath_genmove().
gunnar_1_19.2. Obsolete atari_atari code removed.
gunnar_1_19.1. Bugfixes in the atari_atari code.
trevor_1_19.1. Tuning patch.
trevor_1_19.2. Regression tweeks.
trevor_1_19.3. sgf2tst repair.
