Updated hugs msc projects

[Neil Mitchell]

Hi Brian,

That's not my primary development environment, I don't even have it
installed, so I've never tested it. However, there is nothing
particularly difficult in the new winhugs code compared to the hugs
code, the only additional complexity are resource files. Compared to
the existing hugs code, generating a makefile should be easy - compile
all c files and link.

I'm certainly happy to keep this as a supported build option.

Thanks

Neil
