Added e-sorter.lo and e-selection-model.lo.

2001-02-27  Christopher James Lahey  <clahey@ximian.com>

	* gal/Makefile.am: Added e-sorter.lo and e-selection-model.lo.

	* gal/util/Makefile.am: Added e-sorter.c and e-sorter.h.

	* gal/util/e-sorter.c, gal/util/e-sorter.h: New class.  This is a
	new simple virtual class for use with ESelectionModel.  It
	implements the same set of methods as ETableSorter but the default
	behavior is as if the sorting was a no-op.

	* gal/widgets/Makefile.am: Added e-selection-model.c and
	e-selection-model.h.

	* gal/widgets/e-selection-model.c,
	gal/widgets/e-selection-model.h: New class.  Implements all of the
	semantics of ETableSelectionModel except for the connection to the
	ETableModel.
