I modified the field TT template to check if the Required constraint is set on
the field that's to be rendered and add a required marker. Though I think that
marking fields as required is such a basic task that I think there should be an
easier way to do it (some css class that gets automatically added to Required
fields should be enough). Maybe there is ... Carl? Anyone? :)
