New functions for saving selection state and such.

2002-01-15  Christopher James Lahey  <clahey@ximian.com>

	* e-cell.c, e-cell.h (e_cell_save_state, e_cell_load_state,
	e_cell_free_state): New functions for saving selection state and
	such.

	* e-cell-text.c (ect_save_state): Implemented the new state
	functions.

	* e-table-item.c, e-table-item.h: Use the new cell state functions
	when focusing in or out.  Fixes Ximian bug #14968.
