Subject: Update cli_getFilesList.sh and cli_printActionPreamble.sh:


    - The verification of FILES was moved from cli_getFilesList.sh to
      cli_printActionPreamble, again. 
      
      I thought that if make cli_printMessage output to standard error
      (/dev/stderr) there would be no problem with assigning the
      output of cli_getFilesList to a variable. If some error exist it
      would not be stored inside the variable because assignment is
      done from standard output no standard error. 
      
      I tested this in the shell prompt and seems to work that way
      there, but not inside centos-art.sh. I am missing something
      surely. Anyway, put FILES verifications (that includes whatever
      kind of output) inside cli_printActionPreamble.
