I added some code experimentally to avoid double editing. Whenever a message 
is edited, a "stop" sign is displayed in the message list next to the edited 
messages and a warning is issued on the single message display page. If the 
original editing has been given up (browser closed) one can just ignore this 
message. I prefer this solution in comparision with a real locking, since 
the mechanisms for unlocking a stale message by the administrator is not 
necessary. Get the newest code from CVS, get also themes/default/stop.gif to 
display the stop sign, and let me know what you think.
