Time left until Observer Mode

[Admins]

It's not that simple to add as you might think, since the observer mode is controlled by a script running on another server, and the observer mode algorithm depends on number of players and similar. Like I said before it would be simplier to add something to trigger some npc on the server a few seconds before it happens (or trigger it, and wait 5 seconds before actually switching).
On the other hand switching someone to observer mode shouldn't bug anything, and if there is some problem it might be good to report the exact problem.
