	* src/corba-sheet.c (Sheet_cell_set_font): Use the standard
	procedure to set the font.

	* src/cell.c: deleted finally cell_set_font.

	* src/workbook.c: Reorganization to make the code be a GtkObject.
	Redone the destruction bits of the Workbook.

	* src/workbook.h: Split sheet.h into workbook.h and sheet.h

	* src/workbook.h: Now the Workbook is a GtkObject or a
	GnomeObject, depending on the compilation flags.
