New gnubg preview

[Philippe Michel]

I have uploaded a Windows build of the current CVS sources there:
http://philippe.michel7.free.fr/gnubg/

Barring the discovery of critical bugs, I intent to tag a 1.08 release 
essentially identical to this before the end of the month and build a 
source archive and a Windows installer.

Then I will not commit any changes until the repository is converted to git.


Significant changes since the previous snapshot:

A feature to show how the player's GNU error rate has evolved throughout 
the player's history, as provided by the database records, contributed 
by Isaac Keslassy.

A change to the default cube efficiency ratio used in 0- and 1-ply 
evaluations. This improves cube decisions at these plies noticeably 
(cube error rates are approximately halved) and the repartition of 
errors (premature doubles vs. missed doubles vs. take or pass errors) is 
now similar to higher plies instead of being mostly premature doubles.


Other visibles changes:

Earlier "one click analysis" features by Isaac have added two more 
buttons to the toolbar, and this could make it too wide for some 
screens. Using an icons only toolbar should now allow to work around 
this issue ; every button has a tooltip and the settings are autosaved.

The Japanese translation is almost complete (it was entirely before the 
above changes...).
