Added a bunch of stuff to the TODO list. Put +s before a few of the items

2000-03-04  Christopher James Lahey  <clahey@helixcode.com>

        * TODO: Added a bunch of stuff to the TODO list.  Put +s before a
        few of the items that are finished.

        * test-table.c: Add a button to save the spec file.

        * e-table.c, e-table.h: Add loading configurations from files as
        well as the ability to get the current configuration out of the
        widget.
