SheetObjectGraphics includes the graphic objects we had before.
SheetObjectObject will be the Bonobo objects.

	* src/sheet-object.c: Converted SheetObject to a Gtk+ object.
	Splitted the functionality of the SheetObject into classes:
	SheetObject abstract class;  SheetObjectGraphic for simple drawings;
	SheetObjectFilled for objects that have a fill attribute.

	* src/sheet-object-graphic.c: Implement the SheetObjectGraphic and
	SheetObjectFilled objects.
