Always Flashing "New Message"

[cforce]

I noticed a Flashing browser tab with message "New Message". When sahll this occour normally? I would expect that if i read the message from chat (timestamp wehn i opened the chat window) only new messages after that date will cause the browser tab flashing "New Message", but in our case it flashes all the time.

I am rewriting the JavaScript implementation to address this and also to improve the automatic scrolling when new messages arrive. My original approach is unreliable. I have disabled the new message flashing in the newest commit.
