Author: Mathias Lorente <mathias lorente free fr>

    Add Element::add_child_cdata().
    
    	* libxml++/nodes/element.[h|cc]: Add add_child_cdata(), using
    	xmlNewCDataBlock(), like the existing add_child_text().
    	* examples/sax_parser_build_dom/example.xml:
    	* examples/sax_parser_build_dom/svgparser.[h|cc]: Use the new API.
