GetDisplayVerbs checks if verbattributes exists

Stops GetDisplayVerbs throwing an error if game.GetDisplayVerbs  does not exist. This can happen right at the start of the game (before even the StartGame function is called) if game.pov has been set, though I am not sure quite what the root cause is.
