Changed django.utils.text.smart_split to return strings, not tuples

smart_split_re = re.compile('("(?:[^"\\\\]*(?:\\\\.[^"\\\\]*)*)"|\'(?:[^\'\\\\]*(?:\\\\.[^\'\\\\]*)*)\'|[^\\s]+)')

    Generator that splits a string by spaces, leaving quoted phrases together.

    Supports both single and double quotes, and supports escaping quotes with

    backslashes. In the output, strings will keep their initial and trailing

    quote marks.
