Adjust start up service: remove obsolete mail addresses

* Mail addresses for bosses and office are no longer
  configured in a properties file, so no need to log
  them anymore in start up service.
Replace font awesome css file by cdn file

* NOTE: Only in Firefox the font awesome icons
  haven't been displayed correctly. A reason could
  be that relative paths are used to include fonts.
  When using font awesome by cdn everything is
  alright in Firefox.
