    Build: Fix build with GEGL 0.2+
    
    Newly added operation listing examples was using old API.
    gegl_list_properties was renamed to gegl_operation_list_properties
    Categories and description is now accessed through gegl_operation_get_key
    
    Also store categories and description on the Operation object.
