* Can now filter market items by vocation, level, slot type, and depot items.
* Added new bitwise lib for handling flag operations.
* Can now get/set local player vocation/premium (TODO: spell list).
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
