Create a watchdog to detect when the server has crashed and restart it

[Riot]

Two parts: 1. an exec script that touches a file in /tmp 1. a cron script that calls the script using the first person on the player list every 60 seconds, and also checks if the update time of the file is longer in the past than x minutes ago (5 or 10). If so, it then sends the stop signal, and if the time goes up another two minutes, it sends a kill -9.
