Update `render_getDirOutput.sh':
    
        - Add `trunk/Manuals/Distro' directory to the list of directories
          which add specific information to their paths. In this case the
          distribution manuals add the release number. 
          
          NOTE: The architecture information isn't used by Distro manuals
          so far, but it might be added in the future if needed (just as
          it is done with the `Media' directory inside artistic motifs).
