Fixes [YOCTO #2808]
Added a new section for the closer look at how BitBake creates
images and the SDK installer files. This included the section
itself, a new .PNG figure that had to be added to the figures
directory of both the ref-manual and the mega-manual. Finally,
the Makefile needed to be edited so that the tarballs for the
ref-manual and mega-manual also included the new figure.
