    doc-reference.am: Do not distribute doxygen.css
    
    * build/doc-reference.am (DIST_DOCTOOLS): Remove the deprecated
    doxygen.css from the list of distributed documentation utilities.
    This is unlikely to cause any serious breakage -- modules that
    still use doxygen.css will continue to build just fine.  Only new
    tarball releases will be affected, and even then only when the
    shipped documentation is being rebuilt.
