Removing visual studio projects.

We don't care about them, and I'm not maintaining them. So they die.

It's simple. We kill the batman.
Removing the scripts folder and clearing out some more crap.

Neither of the scripts are at all useful to me and I don't see the point
in having the UnitTest++ directory, so now it's gone.

Also removed the "replace.py" script. Still not sure what it's for.
If I bothered to look in the Makefile, I'd probably get my answer. Not
going to look though, because I like myself as a person too much to look
at a Makefile on purpose.
Replacing Makefile with waf.

This now has compilation, running the unit tests, and installation.
Still need to complete installation by installing the pkg-config file.
pkg-config file and headers are now installed.
