Lots of chagnes to add multi protocol flexibility, not really
completed yet, still have to rework text messages opcodes and other stuff,
so this still a working in progress feature
* Rework dat reader, the dat reader can now
* dinamically detect dat version
* Split game into gamelib and game_interface
* Lots of other minor changes
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
* fix battle rendering
* fix rendering glitch when following creatures
* properly throw exceptions from C++ to lua and avoid exception crashs
* fixes rendering states in framebuffer
* 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
* change in protocol/network classes to make compatible with older protocols
* use filestream for reading dat
* add many ifdefs for multi-protocol support
