Keyboard converter for IBM terminal keyboard

This is a port of TMK's converter/terminal_usb to QMK.

It supports PS/2 Scan Code Set 3 and runs on USB AVR chips such like PJRC Teensy. I tested the converter on ATMega32U4 with 1392595(102keys) and 6110345(122keys).

Data	PD2
Clock	PD5

And VCC and GND, of course. See Resource section for keyboard connector pin assign.
