[Coco] CoCo Cafe error fixed

[Roger Taylor]

Anybody hitting the chatroom this past weekend might have noticed 
Boisy appearing to be online 24/7 for several days.  For a while I 
thought this was a typical lurk mode some chatters stay in, but as of 
Monday evening I thought... wait a minute, something must be 
wrong.  :)  Even a lurker would accidentally browse off the page and 
lose his session since the new chat system doesn't retain sessions 
like the old one did.

I called up phpMyAdmin and noticed that I could not delete the 
session no matter what I tried.  It kept turning up zero rows when 
queried, etc.

After setting the chatter id field to Unique and as the key, I was 
able to delete the stale entry.  I think the chat system either 
neglected to do this on the install, or the script didn't totally 
click with the latest PHP or MySQL rules.  At any rate, it seems to 
be fixed now.
