Refactor the initial identification conversation to use Questions

[curiousdannii]

The initial identification conversation uses scenes and the main turn sequence, which makes it rather convoluted. It would probably be more straight forward to use the Questions extension.

(Possibly Questions may still be convoluted - I remember last time I looked at it that its closed questions feature was not the best it could be. It might even go through the main turn sequence as well. Possibly I will want to implement my own version of Questions.)

Anything we can do to make this less convoluted sounds good to me.

Perhaps we could have a simple way to skip the initial conversation altogether while testing, like some secret command instead of yes/no at the very first prompt?

I am wanting to add a title screen to the game, which would make it easier to go straight to load a new game, go to the menu etc.
