added: support for UTF-8 (files utf8.h utf8.cpp)

they can be even used without the rest library
         as only a library for converting between wide characters and UTF-8
changed: everywhere we use std::wstring instead of std::string
changed: Generator and Functions are templates now
         they take a stream type
renamed: Info to FunInfo and it is a template too
         taking a stream type

now you can use other kind of streams with the library
previous was only std::ostringstream
