Son of Screamer

OK we already have this here essentially with the Lovepedal Eternity, but this was a request and using the Eternity as a template meant it took 2 minutes to do.  This is Jack Orman's circuit which pre-dates the Eternity and so the design that Sean was "inspired" by.  Anyway I suppose it's nice to keep filling the library so we have everything,

Not verified in this guise, but it is really of course :o)

and an 18V charge pump version as requested
