cagou widget: don't add header_input systematically anymore:
header input is often used in CagouWidget for e.g. filtering, but not always, and when it
is not, it is weird and confusing to have a TextInput which doesn't do nothing. To avoid
that, a new `use_header_input` bool attribute (set to False by default) has been added to
CagouWidget.
