Update directory structure holding corporate identity documentation.
    
    - Previously, POT files were retain and under version control. Since
      POT files are only use to create PO files they are considered
      temporal files. This update removes POT files from this directory
      structure.
    
    - Previously, PO files where store in language-specific directories.
      This update moves language-specific directories to a Locales
      directory. This is the convention used by locale module when
      it produces localization files.
    
    - The render.conf file was updated to set the new location of PO
      files.
