More BS2 restructuring.

The various game settings are no longer stored in the Gui class. They are
stored in the class that use them.

Code that doesn't belong in the Gui class, e.g. the "restart" code, has
been moved out of it.

Afterwards, the Gui class had been reduced to nothing more than a handful
of trivial methods for invoking the in-game dialogs. So the entire Gui
class has been removed.
