Update `cli_printCopyrightInfo.sh'
    
        - Start using COPYRIGHT_HOLDER and COPYRIGHT_YEAR_FIRST variables.
          This variables are initialize at centos-art.sh script. With
          this it is possible define different copyright information for
          different applications. 
          
          For example, I'm currently working in two very similar
          applications but for different people (The CentOS Project and
          the Society of Jesus at my city). Each application has its own
          initialization script (`centos-art.sh' and `ispadm.sh'
          respectively). By defining these variables in such
          initialization scripts let me use different copyright
          information through the same rendition code I've been writting.
