A little improvement.

The TONE command should look like:

TONE freq[-finalfreq] duration [shape] [attack,decay,sustain,release]

Shape must be one of: SINE TRIANGLE SAWTOOTH SQUARE (or min. two letter
abbreviation).
attack,decay,sustain,release must be integers in range 0..1000

Default values are:
finalfreq - same as freq
shape - SINE
adsr - 5 0 1000 5

Tone generator may render SINE as TRIANGLE (in fact difference between
sine and triangle is very small)

Question: should we use also 'volume' in command parameters? If not, tone
generator must render all waveforms with same loudness.

examples:

Simple 'beep':
TONE 440 200 

Cue:
TONE 110-660 100

Bell:
TONE 1000 200 SQU 0,80,200,50
