add $format parameter to module_invoke in filter_admin_format_form_submit

Some modules expects an $format to decide if filter has cache (e.g. html purifier)

So, can you change line 202 of filter.admin.inc to:

      $cache &= !module_invoke($module, 'filter', 'no cache', $delta,$format);

please? I can send a patch if you wish.

thanks!
