Ben Harris 860d79c874 kaios: Add hooks for the KaiAds API
The Kai Store makes display of advertisements provided by the KaiAds API
mandatory.  I don't want such adverts to be inconvenient for the users,
so I've just gone for adding a menu item that will display one.  This is
probably a little too crude, but it's good for testing things.

The actual KaiAds API code is not free software, so it's not included
here.  My intention is to add it by hand to the Zip files for Kai Store
uploads.  Without it, the advertising code does nothing.
