[Ifeffit] no plot window with Demeter on Ubuntu 18.04

[Ravel, Bruce]

Hi Joseph,

You did the first few troubleshooting steps.  Good to know that gnuplot 
works by itself.

What is the value of preferences->gnuplot->program ?  On a linux 
machine, this parameter should simply be set to "gnuplot".  That means 
that gnuplot needs to be in the execution path.  Perhaps gnuplot is in 
an unexpected place on your machine?  Or perhaps it is called by an 
unexpected name?  If it is not in the normal execution path, try setting 
that parameter to the full path to the gnuplot executable.

The Gtk-CRITICAL warning is almost certainly a red herring.  That has to 
do with how one of the widgets in the main display gets sized when 
Athena is created.  It is noisy and annoying, but almost certainly not 
harmful or related to your plotting problem.
