Subject: terminal.py: Fix Xfce on ubuntu/debian; some cleanup

    * Xfce class was setting and passing wrong variable for ubuntu/debian.
    * Xfce class was using -e instead of -x for passing command.  The former creates
      a shell escape nightmare
    * Clean up local and instance/class variables with same name but different usage.
    * Remove side-effect and directly return formatted command for clarity.
