CS:GO doesn't send the client name in plain text, but wraps it in some

CSS' CBaseClient::ClientPrintf tries to use the net channel directly
instead of going through the saner route using GameClient::SendNetMsg.
This introduces a stupid hack to work around the bots lack of a net
channel, so ClientPrintf's SVC_Print messages get included in the demo.
