New speakup 'Read All' Command in CVS for litetalk driver

[MICHAEL MCDONALD]

The added code to the drivers should be very simple.  Basically it will
just be reading the index number from the port and the command to output
it.  All the code dealing with the indexes themselves will be dealt with
in the files that apply to all the drivers.  As long as the different
synths work similarly to Litetalk, it shouldn't be too difficult to
update them.
