    Uncap sphinx version

    Sphinx version has been capped since
    I9c45d239e156ec4fb49b5d8bd2404b66155be92b
    in order to fix an issue with resolving citations.

    Then, in I7e55dcf910e0ba6dd85b565db8cb1ecbdd39634a,
    the issue has been fixed by modifying citation references.

    So uncap sphinx version.
    But sphinx 1.6.1 has another issue (*1),
    so leave sphinx 1.6.1 in the blacklist.
