New CAWL Cup Open Registration

[BaDMonkey]

I think these Anti-cheat issues must be addressed, for the main reasons:
1. A lot of players on Assaultcube run on Linux and mac OS.
2. No one wants to install something which we don't know what exactly it is. Maybe if, like waffles suggested, you allowed some developers to view it, and maybe even help to optimize it for AC, or even help you guys bring it cross platform.
