bitbake/depexp: Factor ProgressBar into a separate class in crumbs/

ProgressBar will be useful in other UI elements so make it it's own class.
Make ProgressBar a subclass of gtk.Dialog, rather than gtk.Window, so that we
can suggest the window manager parent the ProgressBar to the widget passed at
as parent.
