taserver release v2.4.0
Bugs fixed:
- implemented a work-around for an unsolved bug to at least not crash the game server
- fixed a problem in counting votes for votekick
- moved xp calculation to the login server
Compatibility notes:
- this release is not backwards compatible; both login server and
game servers must be upgraded to v2.4.0 simultaneously.
After the upgrade a new controller must be downloaded by running
the download_compatible_controller.py script.
