Fixed issue 06165: unable to implement affirmative exclusive non-answer in array_filter_exclude
Fixed issue 06079: sub-question filtering broken if "other" or "no answer" option is given
Dev Array_filter and array_filter_exclude now handle mismatched lists of sub-questions gracefully. Values in list B that are not in list A will not be filtered, and will not throw errors.
Dev This lets authors support exclusive options like "none of the above" in array filtered questions
