Added support for the sorting info. The Etable creates a sort_info object,

2000-03-05  Christopher James Lahey  <clahey@helixcode.com>

        * e-table.c, e-table.h: Added support for the sorting info.  The
        Etable creates a sort_info object, and then connects to the
        signals to rearrange the rows when the sort_info changes.  It also
        passes the info object to the ETableHeaderItem.

        * e-table-model.c: Fixed a typo where ETableModel was written as
        ETableModle.

        * e-table-header.c, e-table-header.h: Added some code for sorting
        here, but it's not used.  I don't think we want this code, but I
        wanted to check it in at least once so that it's not lost.

        * e-table-header-item.c, e-table-header-item.h: Added a
        "sort_info" argument to ETableHeaderItem.  Added display of
        current sort settings.  Added support for clicking to change the
        sort settings.

        * e-table-col.h: E_TABLE_COL_ARROW_NONE is marked as being = 0
        since this is required in other places.  (I think C defines this
        as being the case, but it's good to have the = 0 there so that
        it's obvious that it has to be first.)

        * TODO: Mark sorting as done.

        * e-table-sort-info.c, e-table-sort-info.h: New files for
        containing the xml grouping/sorting information and for sending
        signals on that information.

        * Makefile.am: Added e-table-sort-info.c and e-table-sort-info.h.
