Matthias Clasen ffa112d586 Add an initial focus testbed
This is an attempt to explore differences in GTK+'s and gails
notions of which widget currently has the focus. Since gail
does all its focus updates in an idle, we cannot do the
comparisons synchronously, so just check ever so often in
a timeout.
