I finished updating all the SKng files which means that all of the current 79 images files have been done. Every file now has a bibliography <div> in <back> and the empty elements in the list link to biblio.xml

I commented out the <div> for contributed resources. I will either do them late or else describe what I intend to do in my dissertation.

I added a keyword for Samuel Laing in all the files for Gerhard Munthe's vignettes. Every file now has a keyword for Snorri but that won't always be the case when I expand my sources for images.
