Ticket 49813 - Revised interactive installer
    
    Description:
                  Removed some advanced settings from the install questions.
                  Moved the signal handlers to non-verbose runs.
                  Fixed some mixed case issues.
                  Added option for sample entries.
                  Added "interactive" argument, and restored "fromfile"
                  from "install".
