2008-04-17  Michael Natterer  <mitch@gimp.org>

	Add some infrastructure that will be used soon:

	* app/plug-in/gimppluginprocframe.[ch]: replace "cleanup" list
	by two lists "image_cleanups" and "item_cleanups" and call
	gimp_plug_in_cleanup() if any of them is non-NULL.

	* app/plug-in/gimpplugin-cleanup.c: add private new() and free()
	functions for GimpPlugInCleanupImage structs and add the same
	infrastructure for GimpPlugInCleanupItem structs which are
	currently unused.
