Make changes to image build process so that different
types of images are better supported.  This is used to build
two kinds of images: "opinsys"-images and "puavo"-images.
The first is the image type that has all the Opinsys-brand stuff
and are supported images to Opinsys-customers, and "puavo"-images
is supposed to be more like the "community supported"-edition.
But there will likely be other image types as well, and perhaps
even the above distinction is not going to be a valid one.
