    src/imageloader.cc: fix for -Wsign-compare
    
    src/imageloader.cc:123:22: error: comparison between signed and unsigned integer expressions 
[-Werror=sign-compare]
          for (gint i=0; i<NUM_FILE_TYPE_PIXMAPS; i++)
    
    src/imageloader.cc:256:21: error: comparison between signed and unsigned integer expressions 
[-Werror=sign-compare]
         for (gint i=0; i<G_N_ELEMENTS(categories); i++)
    
    NUM_FILE_TYPE_PIXMAPS = G_N_ELEMENTS(file_type_pixmap_files) (line 54)
    #define G_N_ELEMENTS(arr) (sizeof (arr) / sizeof ((arr)[0])) (GLib)
    
    so both have size_t.
