iocage Helper Script

I found as I replace more boxes with jails, that managing them is getting a little tougher. So I made a simple shell script to do a few things for me. I can update all my jails, remove all the auto update snapshots, execute a command in all the jails, and upgrade all the packages.

I haven't really tested this code much, and of course I have only used it on my setup.

Use this at your own risk!
