Removal of the "unsopported" folder. 

It used to contain a unused sensitivity analysis that
has not been touched for the last 15 to 20 yeras.

We are not a museum. If somebody wants to reactivate
this code, of course it is available within the older
ngspice releases.

/*
* Do remote spice jobs. The first line transmitted will be of the
* format: "user host program". The program field may be left out,
* in which case it defaults to SPICE_PATH. The program is then
* executed, with the single argument "-S". The remote host should
* wait for a response from spiced before sending any data -- so
* far the only response sent is "ok".
* Eventually we will want to deal with load-balancing
* of spice jobs.
