    Bug 792686 - Colormap widget not updated when adding entry
    
    gimp_image_add_colormap_entry(): increment private->n_colors *before*
    calling gimp_image_colormap_set_palette_entry() so it actually adds an
    entry.
    
    (cherry picked from commit 28d9e43f5366a12a86d666a071c490c841d40743)
