[gimp/metadata-browser] app: add parent_type parameter to gimp_gegl_get_config_proxy()



commit 2bfee451b1c1ac808fa050fb8c388921a5bd9224
Author: Michael Natterer <mitch gimp org>
Date:   Fri Mar 30 00:51:24 2012 +0200

    app: add parent_type parameter to gimp_gegl_get_config_proxy()
    
    and derive from that type. Use GimpImageMapConfig as base class for
    GimpOperationTool's config.
