Added duplicate_value and add_value. Use the new compare functions. Made

2000-02-24  Christopher James Lahey  <clahey@helixcode.com>

        * test-table.c: Added duplicate_value and add_value.  Use the new
        compare functions.  Made it so we only create one model to better
        test model view stuff.  Changed the test to not have as many
        extra, useless, columns.

        * test-cols.c, test-check.c: Added duplicate_value and add_value.  Use the new
        compare functions.

        * e-table.c, e-table.h: Use all the new features of e-table-groups
        (sorting and grouping).  Handle on the fly reorganization of
        groups in an idle loop.  Compare functions now are to return -1 if
        the first item is greater, 0 if they are equal, or 1 if the second
        item is greater.

        * e-table-subset.c, e-table-subset.h: Made e-table-subset
        disconnect properly from its signals when it dies.

        * e-table-subset-variable.c, e-table-subset-variable.h:
        Virtualized the add and remove commands so that
        e_table_sorted_variable could override the add command to do sorting.

        * e-table-sorted.c: Fixed this to inherit properly from
        ETableSubset.

        * e-table-simple.h, e-table-simple.c: Added handling of
        duplicate_value and free_value;

        * e-table-model.c, e-table-model.h: Added duplicate_value and
        free_value for memory allocation of table elements outside the
        table.

        * e-table-item.c: Fixed a crashing bug.

        * e-table-group.c: Added sorting.  Fixed destruction to delete the
        right things.

        * e-table-group-leaf.c, e-table-group-leaf.h: Pass column and sort
        order information into the e_table_sorted_variable.  Properly
        destroy things when deleted.

        * e-table-group-container.c, e-table-group-container.h: Properly
        handle the list of subgroups.  Handle proper sorting and grouping
        of subgroups.

        * e-table-sorted-variable.c, e-table-sorted-variable.h: Files to
        do a sorted model that stays sorted as you add and remove rows.

        * Makefile.am: Added e-table-sorted-variable.c and
        e-table-sorted-variable.h.
