altered speakup config tool.

[Steve Holmes]

My next version will differentiate between synthesisers and offer only the
modes (parameters) relevant to that modle. Example: Voice for doubletalk
but speakout doesn't have that one so speakout users would not be given
that option. I also want to add a feature to save and restore settings. I
need to work out the format of that file as most unix style applications
would probably save that info in a human readable format. Then there's the
validation of the saved format - particulary if humans message with those
saved values. So it may be a few days or more before I get that out but
hopefully then I can then have the program in such a way it would be much
easier to add new synthesisers.
