	* app/color_panel.[ch]
	* app/color_picker.c
	* app/qmask.c: removed the public function color_panel_free() and
	fake a real widget's behaviour by connecting to the panel widget's
	"destroy" signal.

	* app/channels_dialog.c
	* app/layers_dialog.c: cleaned up and sync'ed the code where
	possible (without changing the logic).
