scalebutton: Don't derive from GtkButton

Browse Source 
Make GtkScaleButton a widget that has a toggle button
as a child, just like all the other button widgets now.
The immediate benefit of this arrangement is to avoid
the "double focus" problem when we pop up the popup.

Update accessible, demos and tests to match.
