Knockout and  Socket.io realtime communication for admin

Thanks for giving me push access!
This update is a little cray cray though, so I'll pull request you for this one, so you can tell me what you think first haha.

Socket.io + Knockout js

Identical implementation as Print Shoppe, but with a lot of cruft removed which wasn't needed due to the update/notify posts being proper requests.

*** note you will need to npm install again *** argh.

😱
Whoops, I'm dense. I wasn't hitting update. The color changed and I was like "OH YAY I'M DONE". I guess that's my queue to go to sleep :sleeping:
