Ticker added to demo site

I recently noticed, from my admin logs, that there was one unfortunate user who created a number of categories and containeris on the demo site, a mere two minutes before the site was reset. This user had no way of knowing when the reset was going to occur, and was probably more than a bit annoyed when all of his/her content vanished much sooner than he/she probably expected.

To avoid problems like this in the future, a 'ticker' has been added to the master template of the demo site. This ticker tells you how much time is remaining until the next reset. So now, if there's only 5 minutes to go, at least you'll know that if you wait 5 minutes, it will be much more worthwhile.
