Multi-protocol

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
