Use unique_ptr instead of scoped_ptr (from boost) (#982)
Use unique_ptr instead of scoped_ptr (from boost) (#982)

When using newer gcc versions, the released version 0.10.6 inexplicably
referred to std::scoped_ptr, which is in boost. The master version of
this code uses unique_ptr (See
https://github.com/open-source-parsers/jsoncpp/blob/master/src/lib_json/json_reader.cpp#L57,
https://github.com/open-source-parsers/jsoncpp/blob/master/src/lib_json/json_writer.cpp#L78
), so use that as well.
