- clarified documentation for keep_off_wget_user_agent
- Added example ece-install.conf which will:

   * set up a presentation server, downloading ECE & plugins + Assembly
     Tool from Technet.

   * Make the above presentation profile use a provided WAR file for
     creating a publication definition in the abovementioned
     assemblytool, which again will be deployed on the new
     presentation server.

   * Make sure the above presentation server gets the correct host
     context defintion for your publication.

- added more hints to the listing of fai_publication_name and _war
  in the mange page; what these parameters can be used for.

- added feature to content-engine::set_up_assembly_tool:
  it will now  set up a publication definition based on the
  fai_publication_name and _war settings.

  We only support one publication for now as it's becoming more and
  more seldom to set up AT with ece-install. Instead, more and more
  folks are using pre-built EARs to make the deployment as a part of
  the ece-install process). Future enhancement would be to support
  fai_publication_domain_mapping_list and
  fai_<presentation|editor>_ear for creating publication definitions
  and WARs.

- removed support for fai_publication_war_uri_list as this is obsolete
  now that we've got the fai_<profile>_ear parameter.
