[sudo-sys] updated DNS for room.sudoroom.org

thanks to Marc for getting cgi working on the new router, and thanks to LMI for going down exactly as Marc was doing that, forcing me to bike my physical body to the omni commons, to discover that the DSL modem was just sitting there being stupid, with only two LEDs on and both DSL LEDs off. power cycling the DSL modem brought LMI DSL back up. After putting a new ssh key into the front door computer, and editing the dooropen.sh CGI script a little bit, door access seemed to work from the new router. I also got the open-sudo-door.py working and tested. I changed the DNS at digitalocean to point room.sudoroom.org to the new router, but I'm not sure I got the IPV6 address correct. I just copied something from "ip a" that seemed to work with ping and telnet, and hopefully it has the right number of colons in it. The ipv4 address was straightforward. Since we're still waiting for 28800 seconds to elapse (8 hours) the old LMI router is still answering requests to open the door, so I modified its cgi scripts to log into the new router and cause the door to open. I'm sure a lot of people will need that. i created a new DNS record for lmi.sudoroom.org to point to our old IP address in case we need that for some reason. But I think we should cancel LMI right away. I also moved the house network over to the new router and tested that omnicommons wifi works, and it's fast now. -jake
