[Maxima] changing maxima display to plaintext notation

[Richard Fateman]

depending on what you use for a computer, it may be possible to use a lisp
program that speaks math.
a program I use happens to use SASDK/SALT from Microsoft Windows, but it is
not part of maxima now.

There is also a program called MathSpeak; http://www.mathspeak.org which I
have not used, gut I don't know if it work with maxima.
