[GreenKeys] USB-teletype adapters

Yeah, the autoprint thing was a bit of a last minute addition. It will accept
backspaces for correction but that's about it. I had imagined people would just
type and edit text in Notepad or something and then cut-n-paste it via a terminal
program. 

Since it sounds like a lot of people would like a more feature-filled autoprint
solution, I've been thinking about a way to do it. Using a Raspberry Pi or other
small single board computer, a couple of switches, and one of these interface
boards might be the way to go. You could put text on an SD card and have it print
to the loop when a button is pushed. More buttons, more choice of texts to print.
Raspberry Pi Zero is <$20 and more than sufficient for the task. I'll look into 
a basic setup that could be installed to accomplish that.
