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

--> Can a stunned piece capture? Maybe not. ...recover? After 5 moves? Never?
