lib/bb/ui/crumbs/hobwidget: convert button styling logic to static methods 

The design calls for all buttons to match the style of either the HobButton
or HobAltButton classes, therefore implement the styling logic as static
methods of the implementing classes so that we can more easily set styles
for the buttons created by a gtk.Dialog (or subclass) without having to
modify too much of the dialog instantiation code.
