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
* Split game module into game and game_interface
* Move core_lib to corelib
* Move miniwindow to corelib
* Introduce init.lua script for initializing the client, giving much more flexibility
* OTClient is no longer Application derived and is much simpler
