No geometry Attribute

The frame, toplevel, and listbox widgets no longer have a geometry attribute. Use the width and height attributes instead. The geometry attribute got confused with geometry specifications for top-level windows. The use of width and height is more consistent. Note that for listboxes the width and height are in terms of lines and characters, while for frames and toplevels it is in screen units.
