Reorganized Makefile with libqhull based on libqhullstatic-p
The application builds well, but, as before, neither the pro
files nor the vcproj files build a good dll using devstudio
Dropped libqhullp. It does not make a large difference
Switched user_eg as the libqhull example.
Fixed LIBQHULLSP_OBJS. Moved shared library to lib/...
Set Version to 6.0.0
