Fill out the server-configuration section.

  We've added two sections on setting up the central server, one
 using git/github, and one using HTTP.
  Added border around examples.

  Also some padding, for neatness.
  Removed leading whitespace from examples.

  This stops the pointless indentation.
  Added stub chapters for future work.

  Chapters 4-7 are now added, but they need more work and appropriate
 subdivisions creating.
  Added some text on the running side.
  Updated the client-chapter.

  Show how to launch the tool, and document some of the
command-line-flags.
