	* app/actions/gradient-editor-commands.h: added enum for the
	"load_color" actions.

	* app/actions/gradient-editor-actions.c
	* app/actions/gradient-editor-commands.c: use the new enum instead
	of magic values, cleanup.

	* app/actions/palette-editor-commands.c: cleanup.

	* app/widgets/gimpbrusheditor.c
	* app/widgets/gimpdataeditor.c: cleanup.

	* app/widgets/gimpgradienteditor.c: added GtkObject::destroy() and
	GtkWidget::unmap() implementations which destroy the color dialog.
	Destroy color dialogs by cancelling them via gtk_dialog_response(),
	so temporarily changed colors are restored correctly. Refactored
	my last commit below a bit. Various cleanups.

	* app/widgets/gimppaletteeditor.[ch]: no need to remember the
	buttons in the GimpPaletteEditor struct.
