    plug-ins: implement RGBE exporting through GEGL.
    
    While we are at it, let's just add RGBE exporting. It's just as easy.
    
    Also rename s/file-gegl-load-rgbe/file-load-rgbe/. All formats just use
    the "file-FORMAT-(load|save)" naming for their procedure, even when
    implemented directly through "gegl:load|save".
