	* app/core/gimpcontext.[ch]: simplified everything a lot by
	merging the public GimpContextPropType enum with the internal
	anonymous object property id enum. Removed the internal copy_prop
	functions and handle property copying in a big switch() in
	gimp_context_copy_property(). Removed the separate signal
	connections for each property of the parent context and do the
	same using a single "notify" handler. Emit "notify" signals all
	over the place.  Removed internal arrays which are no longer
	needed due to enum merge and copy_property simplification.
	Removed the array of signal names and use g_signal_name().
	Removed gimp_context_unset_parent() and allow "parent" being NULL
	in gimp_context_set_parent().

	* app/tools/tool_manager.c
	* app/widgets/gimpdevices.c: changed accordingly.

	* libgimptool/gimptooltypes.h: changed GimpToolOptionsGUIFunc to
	return a GtkWidget (the created tool options widget).

	* libgimptool/gimptoolmodule.c: #include <gtk/gtk.h>

	* app/tools/tool_options.[ch]: removed the "main_vbox" from the
	GimpToolOptions struct. Changed gimp_tool_options_gui() to create
	and return the main_vbox.

	* app/tools/tool_manager.c: create the "This Tool has no Options"
	label here if NULL was passed as "options_gui_func". Attach the
	options widget to the tool_options object using
	g_object_set_data().

	* app/gui/tool-options-dialog.c: changed accordingly.

	* app/tools/gimpairbrushtool.c
	* app/tools/gimpblendoptions.[ch]
