Update trunk/Scripts/Bash/Functions/Path functionality:
    
        - Separate info, html, and plaintext export actions into
          help_updateOutputFileInfo, help_updateOutputFileHtml,
          help_updateOutputFilePlaintext function scripts respectively.
    
        - Use help_updateOutputFiles functionality as base location to
          call specific export functionalities.
    
        - Before doning any export action, move into /home/centos/artwork
          using directory stack in order for makeinfo and Texi2html to use
          the correct path information when files are exported. 
          
          As convenction, all paths inside texinfo documentation are set
          using trunk/ as root location (without leading slash).  
          
          Using /home/centos/artwork (without trailing slash) grants
          makeinfo and Texi2html to join both locations to build the final
          image path correctly.
    
        - Update comments inside function scripts.
