Ticket 332 - Command line perl scripts should attempt most secure connection type first
    
    Bug Description:  If you set the server to only allow secure binds, all the instance
                      scripts will fail to run.
    
    Fix Description:  The scripts will now check for the most secure protocol available
                      to connect to the server.  The scripts now work with both mozldap
                      and openLDAP clients.  Improved config parsing and protocol
                      checking/failover.
    
                      Improved the exit status of the scripts, made all the "usage" output
                      consistent, and other minor improvements.
    
                      Also did major cleanup of the indentation in all of the scripts.
