[Defconapi] Extensive use of SendChatMessage 3

[Robin Baumgarten]

Hi Jakub,

That's an odd behaviour, I shall investigate that. Also, I have read
something about spam-prevention in the Defcon source-code. If you want I can
look up the details and see if it causes the slow-down.

Meanwhile, did you have a look at DebugLog()? This is probably a better
method for outputting debug information.
