Added largely extended userguide with some images into subfolder of doc folder.

• Munched docbook into something workable:
  • the big problem was out-of-source build in conjunction with the figures in the userguide.
  • I did not try hard enough with img.src.path but used entityref instead together with a catalog file.
  • so in all, we have followed:
    • ​http://movementarian.org/docs/docbook-autotools/index.html
    • ​http://www.sagehill.net/docbookxsl/GraphicsLocations.html
  • ... this was a long way ...
  • am_conditioning on both xsltproc and fop.
