Handle verification error timeout

[inoryy]

When a game takes longer than 120 seconds then server responds with:

{"error":{"id":75,"message":"Verification process has elapsed"}}

At the moment this is only specific to CSB, since games there can potentially take: (2 bots x 0.15 ms x 500 turns) = 150 seconds.

To replicate, launch a game with two top 20 bots, which are close in ranking (i.e. RiSuS vs MadKnight) on a 5-6 checkpoint map.

Resolution ideas:

• throw away the game and restart from a new map
• Wait 30-35 seconds and retry with same game options

I've tried several times to reproduce the problem in the past few weeks, and I can't do so. I assume that CG has repaired the timeout issues on the server. Since I can't see it happen right now, I don't think I can do anything to fix it.
