add icon_at virtual function - it was stupid to make the insert call take

2000-06-23  Chris Toshok  <toshok@helixcode.com>

	* e-tree-model.h, e-tree-model.c: add icon_at virtual function -
	it was stupid to make the insert call take 2 pixbufs.  the model
	should give this information.

	* e-cell-tree.c: get rid of the opened/closed pixbuf stuff.  call
	e_tree_model_icon_of_node.

	* e-tree-example-1.c: add my_icon_at.

	* e-tree-simple.c (simple_icon_at): new function
	(e_tree_simple_new): add icon_at parameter.

	* e-tree-simple.h: add SimpleIconAtFn.
