[Box-Admins] The squeaksource.com SqueakSource image is now controlled by supervise(8)

I have put the squeaksource.com image under the control of supervise(8) on box3.squeak.org. The service name is "ssdotcom" and it should now be controlled by svc(8) run by root in the /etc/service directory.

This replaces the the homebrew runimage.sh supervisory script that that I had written initially in order to bring squeaksource.com on line. That script will now issue a message informing the user of the change.

Everything seems to be working properly now. I will keep a close eye on it for the next few days to make sure it stays that way.

Assuming that no new problems arise, this completes the transition of squeaksource.com from its original home at SCG to its new home at squeak.org.
