Implement these functions as pass through to the child cell.

2001-10-10  Christopher James Lahey  <clahey@ximian.com>

	* e-cell-popup.c (ecp_get_bg_color), e-cell-tree.c
	(ect_get_bg_color): Implement these functions as pass through to
	the child cell.

	* e-cell-text.c, e-cell-text.h (ect_get_bg_color): Implemented
	this using a bg_color_column which can be set through the argument
	of the same string.

	* e-cell.c, e-cell.h (e_cell_get_bg_color): Added this function to
	allow background color to change by cell.

	* e-table-item.c (eti_get_cell_background_color): Call
	e_cell_get_bg_color to allow background color to change by cell.
