Seems to fail a little bit with nodewords "Dublin Core date"

Issue Summary

There may be an easy fix, but right now when used with 'nodewords' enabled, almost everything can be turned off except the "Dublin Core date" - which seems to be an oddly structured form element and not detected as something which can be disabled.
I can turn off the individual select elements, but still see the element title on the page.

A bit awkward.
It MAY be just a question of adding the 'date' form element to formfilter_supported_types()

Yep, that works!
