Verify player data when games are hosted

[duk3luk3]

We are now at a point where a handful of people is aggressively exploiting our lack of verification of data passed to forever.exe, i.e. name and rating.

It should be possible to verify that on the server, and we should do so and kick players who exhibit discrepancies.

This is more of an fa issue since the exe currently has no way of actually reading data sent by the server.
