Object conversions return the specific type that was converted.

This allows us to easily make function calls that have parameters that are dependent
upon converting from msgpack objects to concrete types. For example:

    void process_args(std::tuple<int,std::string>& args)
    {
        ...
    }

    process_args(obj.convert(std::make_tuple(100,"hello")))

You can get similar behavior by using obj.as<...>() but its performance is highly
dependent upon the specific compiler and whether or not r-value references are
supported.
