Update locale module of centos-art.sh script.
    
    - Previously, the locale module used the --type option to establish
      the kind of file processing to do, based on the file provided in the
      command-line. This option accepted three values (self,siblings and
      all). This design makes me write to much in the command-line. This
      update changes the locale module to remove the --type option and
      using the --siblings and --all options instead. The --self option is
      not set as possible argument in the command-line because that is
      locale module's default behaviour with processing files.
    
    - Previously, the --update, --delete, and --edit options didn't have a
      short version for them. This update changes the locale_getOptions
      function to support the -u, -d and -e as short options for --update,
      --delete, and --edit options, respectively.
