Make otclient's framework flexible enough to run console apps like
servers, so this mean is possible to build otclient versions without
graphical interface and use it's framework to code servers

* 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
* change in protocol/network classes to make compatible with older protocols
* use filestream for reading dat
* add many ifdefs for multi-protocol support
