PLEASE TEST IN WINDOWS 7 AND WINDOWS XP BEFORE MERGING
Update windows solution files to VS 2017.
This also removes the MASM build commands from the zlib project. Having
this only makes buiding the source harder for new users, and it
ultimately isn't necessary.
The changes also rearrange the snesn9x project's <IncludePath> and
<LibraryPath> from (Include);(DirectX);(Cg) to (DirectX);(Cg);(Include).
These changes reflect the original library path order. The modification
I made beforehand could have affected XP builds and I didn't have a
chance to test this before merging.
