Update trunk/Scripts/Bash/Functions/Path functionality:
    
        - Remove -I option from info and plaintext output. Before output
          info and plaintext information we moved inside
          /home/centos/artwork directory which is the base location for
          paths inside texinfo documentation files. There is no need for
          info and plaintext output commands to specify the -I options
          since the command already takes place in the correct location
          the path information is correctly built on.
    
          Nevertheless, the -I option is still required for html output.
          Once inside /home/centos/artwork we need to move up to html
          output directory in order to run texi2html output command from
          inthere. This make texi2html to set relative path to images
          when html output is generated. 
          
          Relative path to images under html output directory will fail
          since there is no image in such location. Instead, a different
          absolute location is used. So we need to build that absolute
          path in order for images can be shown as we expect.
    
          So this why we still need to use the -I option. We use the -I
          option to append the location /home/centos/artwork to texi2html
          search path; and because we use @image{} definition using trunk/
          as root location to define images location ... texi2html is able
          to find the correct path to image, no matter where you execute
          the centos-art.sh help command.
    
          Note that we keep images and documentation output in two
          different absolute locations. This is intentional. Such
          configuration let us maintain documentation and images
          independently one another.
