New list class with iterators.

2000-07-03  Christopher James Lahey  <clahey@helixcode.com>

	* e-iterator.c, e-iterator.h, e-list-iterator.c,
	e-list-iterator.h, e-list.c, e-list.h: New list class with
	iterators.

	* e-canvas.c: Made it so that you don't get the same selection in
	the selection list more than once.
