	* app/widgets/gimpchanneltreeview.c: implement
	GimpDockedInterface::set_context() and set the context of the
	embedded GimpComponentEditor. Fixes NULL-context crashes in
	action callbacks when invoked from the component editor.
	Spotted by Jimmac.

	Unrelated:

	* app/widgets/gimpitemtreeview.c: get rid of the
	gimp_item_tree_view_context_changed() callback and
	g_signal_connect_swapped() gimp_item_tree_view_set_image()
	directly.
