Copie figée du cœur de GNU Backgammon (commit 14b6798)

Fichiers repris sans modification dans engine/gnubg/, poids et table
d'équité Kazaross-XG2 dans engine/data/, provenance détaillée dans
engine/gnubg/PROVENANCE.md. Le lint ne vérifie plus les espaces de ces
copies, pour qu'elles restent identiques à l'original.
