Added functions to convert from view row to model row or from model row to

2000-08-05  Christopher James Lahey  <clahey@helixcode.com>

	* e-table.c, e-table.h: Added functions to convert from view row
	to model row or from model row to view row.  Also changed
	e_table_set_cursor_row and e_table_get_cursor_row to take a model
	row as this works better with the rest of the model.  Changed the
	name of e_table_get_next_row_sorted and
	e_table_get_prev_row_sorted.  (Dropped the _sorted.)
