Connectivity fixes and performance optimizations

Helloooooo CardMeeting ppl,

The network is starting to resemble the harmonious flow of data I have always believed was possible.

Over the Easter weekend, I found myself drawn into a tuning effort that centered around network traffic going into and out of meetings. In the process I found many bugs that related to huge packets killing connections, rendering problems, and even a potential data loss bug due to a framing issue I found!

I got the build wrapped up and tested tonite and the build I just placed on the server is looking good. I don't see any more random "radio tower" warning icons, there's no more bizarro CPU spikes on the servers, no more crazy packet storms. Best of all, the traffic when nothing is going on (which is like 99% of the time), is almost nothing... In the past, the server and clients were constantly chatting, and it strained my limited bandwidth even when every meeting was idle! It all just "feels" more solid now. I know better than to claim the thing is bugfree, but it sure is better behaved than it was last week.

All this means CardMeeting can now host more users, I'm hoping you all can get the word out and make the login roles swell a bit more. I'd like to stress the server out more and see what the new limits are.

Please give what I've got up there a whirl, and then please let me know, good or bad, what your experiences are with this build.

Thanks for using CardMeeting,
