Hi all,

I've added support for Hugh Sconyer's full 15x15 bearoff database in
gnubg. There are still a few glitches, so I consider this feature
experimental. One of them is that you need to issue the command 

set bearoff sconyers 15x15 dvd path "D:\\"

(or whatever your DVD drive is called) before you can use it. 

There is a new menu entry "Analyse->Bearoff Database" that brings up a
dialog. If the current positions a bearoff position you can see the
equities of the position, or if there dice are rolled: the equities
after the best move. Currently, this feature works with Hugh's 15x15
bearoff database (on DVD or disk), gnubg's own two-sided bearoff
database, and gnubg's own hypergammon databases. 

For users with huge disks I intend to add support for using the 15x15
bearoff database in evaluations and analysis. I've written the code, but
it's not enabled as I still need to debug it -- also I need a 50 GB disk :-)

I intend to add support for Hugh's backgame database and race database
as well.
