	Implemented "Snap to Canvas Edges" (fixes bug #152971) and
	"Snap to Active Path" (half way done):

	* app/core/gimpimage-snap.[ch]: added boolean snap_to_canvas and
	snap_to_vectors parameters (snap_to_vectors works fine when
	snapping to a point, but is unimplemented for snapping to a
	rectangle).

	* app/display/gimpdisplayshell.[ch] (struct GimpDisplayShell):
	added snap_to_canvas and snap_to_vectors booleans.

	* app/display/gimpdisplayshell-appearance.[ch]: added API to
	get/set them.

	* app/actions/view-actions.c
	* app/actions/view-commands.[ch]
	* app/widgets/gimphelp-ids.h: added actions, callbacks and help IDs.

	* menus/image-menu.xml.in: added them to Image->View.
