Update umod integration with ./rustserver update

Could you integrate mods-update with the update command? So when you run ./rustserver update it will automatically update umod as well?

This would make it a lot easier to integrate with cron. Also possibly add it to autoupdate on startup but that seems to be seamless. So if you could update the script that would be nice :). Or a workaround would be fine as well, as long as it works with the autoupdate on startup.
