Subject: Update tcar_printHelp file.


- Previously, the tcar_printHelp function failed to print script
  documentation. The condition set when tcar_printHelp message is
  called from centos-art.sh script isn't retrieving the correct
  documentation name. This update changes the tcar_printHelp.sh file
  to retrieve the correct documentation file when tcar_printHelp is
  called from centos-art.sh script and there isn't any module name
  defined yet.
