[conquest] 8.1b (not public) and john's UDP issue

[Jon Trulson]

  	I have put up a 8.1b in the tx/ area (not publically available 
yet).  One bug fixed and a feature that might help with john's 
'dissappearing UDP' issue.

  	- during playback of a recording, honor the user config
            NoRobotMsgs option.

  	- test UDP keepalive to see if johns 'disappearing UDP'
            problems disappear.

  	  The theory is that since outbound (client->server) UDP packets 
are never sent after the initial UDP conn is negotiated, what john is 
seeing is that after some time (about 10 minutes) of no outbound packets 
on the UDP connection, his firewall is just dropping the udp connection 
(assuming it's dead), thereby stopping ship motion UDP from coming in over 
it.

  	  This change has the client (only the GL one for now) send 
periodic 'keepalive' packets to the server on the UDP connection every 60 
seconds or so, hopefully convincing the firewall that the connection is 
still valid.  The servers have been updated to 8.1b as well so they won't 
bitch about the unknown packet type (CPCMD_KEEPALIVE) coming in.  The 
packet itself is just ignored server-side.

  	  Let me know when you want to try to test this.  I would 
recommend connecting to the dev server with your current 8.1a client, and 
timing how long it takes for UDP to stop working.  Then try the 8.1b and 
see if it continues to work after the expected time expires.

  	Has anyone else seen this problem with ship motion data, etc just 
'stopping' after some time in the game?

  	If it works, I'll clean it up for an official 8.1b public release. 
If it doesn't, I guess some more investigation is in order :)

  	I am available for Conquest today and/or tommorow, of course :)
