Fix InsetListings::getCaption() for std::regex

Browse Source 
Back references in the format string of regex_replace use the syntax $n both
in std::regex and in boost::regex for the default format. Boost seems to
support the syntax \n in addition, but it is not documented at
http://www.boost.org/doc/libs/master/libs/regex/doc/html/boost_regex/format.html.
Therefore it is a good idea to use $n also for boost.
