[GreenKeys] Baudot code variations

[William Bytheway]

A little history, goes back to the year 2000 :

The RTTYApp code was written to support the WA9XHN Special 
Temporary Authority (STA) to establish and operate a 1000-watt 
Radio Teletype (RTTY) Broadcast Station on 6994KHz and 13972KHz.

Modes supported were Military, ITA#2, TELEX and ASCII, Baud
rates were 45.45, 50.0, 56.9, 74.4, 100.0 and 110.0. The tables
below were a part of the original source code.  George, W7TTY
primarily used military, 60wpm and 100wpm.
 
The source of the Baudot conversion data I used can be found at:

I've re-attached the notes to the code snippit below. Also
renamed the last column, since it shows the mark/space code.
The military column was added by looking at the keyboard of
my own M28.
