Standardize Theme/Motifs/TreeFlower/3/Concept directory structure:
    
        - The TreeFlower logo is no longer used. Instead we are using just
          the name TreeFlower, as in the Theme/Motifs/TreeFlower/3/ path.
          The reazon for this change is that: 
          
          In the sake of optimizing image production, all concept-releated
          design templates were moved up to Theme/Models/ directory
          structure, and so made common for all artistic motifs. As
          consequence, the name used inside design template to show the
          theme name is built dynamically, based on the path information
          of the theme currently rendered. So there is no chance for extra
          designs when we build the $THEME/Concept directory structure.
