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
