Update render_doIdentityImageBrands.sh:
    
        - Before this commit, '*.xbm' and '*-emboss.png' images produced
          by render_doIdentityImageBrands post-rendering action were
          stored all together in the same location. 
          
        - In this commit, '*.xbm' images are stored inside Xbm/ directoy
          and '*-emboss.png' images under Png/ directory. If these
          directories doesn't exist they are created by centos-art.sh
          script.
    
        - The moving file functionality is marked to be unified in
          centos-art.sh path functionality. Run the command `centos-art
          help --read=trunk/Scripts/Bash/Functions/Path', for more
          information.
