Add a "row_selection" signal.

2000-03-06  Christopher James Lahey  <clahey@helixcode.com>

        * e-table.c, e-table.h: Add a "row_selection" signal.

        * test-table.c: Test the new "row_selection" signal.

        * e-table-group-container.c, e-table-group-leaf.c: Implement the
        "row_selection" property properly.

        * e-table-group.c, e-table-group.h: Add a "row_selection" signal.
