dev-cpp/pystring: New package

Pystring is a collection of C++ functions which match the interface and
behavior of python's string class methods using std::string. Implemented
in C++, it does not require or make use of a python interpreter. It
provides convenience and familiarity for common string operations not
included in the standard C++ library. It's also useful in environments
where both C++ and python are used.
