Replaced whiptail, moved OctoPrint, added plugin manager

Replaced whiptail with dialog since dialog has more features and looks
nicer imo

OctoPrint has been moved to /srv/octoprint

There is now an OctoPrint group as well as an OctoPrint user

First-time will now ask if you want to preinstall some curated plugins

Added warning advising end users that this is nowhere near production
ready.

Added more stuff to TODO
