   1 Issue: embedded rules language not updated when language is set (in Analyse, Game and Problems)
   2 Also: if new live game starts in background, "new game" notify OK but not first move (not too serious however)
   3 On smartphone for Teleport, Chakart, Weiqi and some others: option "confirm moves on touch screen"
   4 (=> comme pour corr) + option "confirm moves in corr games"?
