Add the OpenGX Glasses

So, first you need to put glasses into a computer in order to flash the
prom. Get the prom package using oppm (oppm install prom) and use "prom
flash [code] ([data])" to flash the connected device. Upon startup, the
only available things are: gx, bootfs, tmpfs, and term. Use term.init to
set up a terminal on the gx. Use term.update to update the terminal so
it can send out the fifo and stuff. term.resolution reports back
resolution, also lets you set it. term.cursor is the same way.
term.write writes text, term.clear clears the terminal. A modem is also
built in (it just isn't proxied upon startup). There is a button event.
It goes like this:
"button" "action1|action2|actionmod" true|false(held). The default
buttons are: O, start computer, hold to turn off; P, toggle screen; [,
action button 1; ], action button 2; Right Shift, action button mod.
