Add e-table-scrolled.c and e-table-scrolled.h.

2000-07-09  Christopher James Lahey  <clahey@helixcode.com>

	* Makefile.am: Add e-table-scrolled.c and e-table-scrolled.h.

	* e-table-item.c: Make sure that find_cell returns FALSE if the
	item doesn't have any cells.

	* e-table-scrolled.c, e-table-scrolled.h: Added a widget to
	contain an ETable and provide scrollbars (for ease of use.)

	* e-table.c, e-table.h: Make this support the scrollable interface
	and not contain its own scrollbars.
