* use shared_ptr for InputMessage and OutputMessage and bind them
* allow sending network messages from lua
* implement extended opcode
* use own OS type  for otclient to allow server side detection
* fixes in input event bot protection
* move RSA to input/output network messages
* allow to capture opcodes before GameProtocol parsing with the event GameProtocol.onOpcode
* fixes in lua std::string pop/push to allow byte buffering
