Enable building the CubeView demo w/o requiring '<config.h>'
This allows to build the CubeView demo from the unmodified FLTK sources
w/o having to provide a 'config.h' file by defining HAVE_GL=1 on the
compiler commandline. See also comment in test/CubeView.h.
test/CubeMain.cxx: don't include <config.h> at all (not needed)
test/CubeView.h: #include <config.h> only if HAVE_GL is not defined
