Subject: Added "table_selection_model" argument. Removed foreach function and

2000-07-26  Christopher James Lahey  <clahey@helixcode.com>

	* e-table-group-container.c, e-table-group-container.h,
	e-table-group-leaf.c, e-table-group-leaf.h: Added "table_selection_model"
	argument.  Removed foreach function and selection notification.

	* e-table-group.c, e-table-group.h: Removed foreach function and
	selection notification.

	* e-table-header.c: Fixed header width calculation to include the
	last column.

	* e-table-item.c, e-table-item.h: Fixed this to use the new
	selection model.

	* e-table-scrolled.c, e-table-scrolled.h: Removed selection
	notification.

	* e-table-selection-model.c, e-table-selection-model.h: Finished
	notification signals and fixed a bunch of bit manipulations.
	Implemented do_something method.

	* e-table.c, e-table.h: Create an ETableSelectionModel and use it
	properly.
