I created a new chat module GUI, which is using ajax to update messages.

The GUI is pretty rough currently, I will continue to optimize it.
And to improve performance, table structure changed, see MDL-11899.

UI changed.

Please do *disable* firebug when you are using it, because too many ajax connection may crash firefox.

I am planning to add cache to chat module to improve performance, this is the plan:

Before insert the new chat message into database, push the message into a cache file (/dev/shm, which can hold 100 messages), when user request the lastest messages, we compare the oldest messsage's timestamp $a with user's timestamp $b, if $a<$b, directly response messages in cache, otherwise, fetch the messages from database.

Any advice?

1. Improve GUI
2. Use /dev/shm to cache users list (UNIX) only, this can improve performance (I will cache latest user messages later)

Will this fall back to alternative methods on Windows servers?
