Update locale module of centos-art.sh script.
    
    - Previously, PACKAGE_NAME inside directory_getConfiguration was set
      to RENDER_FROM basename. To prevent confusions, this update changes
      the directory_getConfiguration function to use ${SOURCES[0]}
      instead. This is the first possible value passed to RENDER_FROM.
    
    - Previously, PACKAGE_NAME and PACKAGE_VERSION were available only
      when processing directories. This update changes the file function
      to add both PACKAGE_NAME and PACKAGE_VERSION to it. So, the
      information they provide is now available when processing files, too.
