prevent heroku instance from sleeping

[timoschilling]

demo.activeadmin.info has a long startup time on heroku, thats sometimes results in a timeout, if the instance starts up in a request.

We should us a monitoring service like new relic to monitor the app, they ping demo.activeadmin.info each minute and prevent the app from going to sleep. That should resolve all the new 'demo page down' tickets.

I've got a service that pings demo.activeadmin.info every 5 minutes. Uptime doesn't look good though...

If greg or you give me access to the heroku app, I will try to find the problem.
