Restore squashed question_types (number, date, file upload, text box, label)
	modified:   lib/surveyor_gui/models/question_type_methods.rb - was incorrectly
	checking display type for these fields when the relevant data was in the first answer
	record in the response_class attribute.

	modified:   spec/support/surveyforms_creation_helpers.rb - modified with .question_type_id to be
	.question_type.
