Fix makefile for the AtomSpace visualizer implemented by Erwin

I'm merging this based on trust. I have no clue what this thing does; it doesn't use the standard CMake infrastructure, and that's bad.  It doesn't have any unit tests, that's also bad.  If this thing actually works, you should post some how-to instructions for it, and some screen-shots for what it looks like.
