A *.dsp file for CallbackMaker in the demos.
Plus updated *.dsp and *.dsw files to reflect the new freeglut header
file.
NOTE: The prior version of the *.dsw file does not in fact have CRs. I
thought that it did. For consistancy, I am not putting them in in this
version, either. (At least one person said that his MSVC++ system is
happy with the current files. If there are problems, we can easily add
the CRs, but that should be a separate commit...)
