	* app/dialog_handler.c
	* app/fileops.c: Various bugfixes and speedups w.r.t.
	thumbnail loading.  Now has a 'generate thumbnail' button.

	* app/brightness_contrast.c
	* app/color_balance.c
	* app/curves.c
	* app/hue_saturation.c: Changed some gint to gint32.  It
	doesn't matter right now, but it might if the optimized
	CLAMP0255 gets fixed.
