Enblend-Enfuse 4.0 prerelease - Windows

[Yuv]

Thanks to Thomas Modes, the tip enblend-enfuse now builds on Windows.
I fired up my Windoze partition and could build it (although my SDK is
a patchwork and I still had to use lcms-1.17. I would need help to
build lcms-1.18 on my Windoze).

On Ubuntu and with dual or quad core CPU, the new enblend-enfuse rocks
big time. It is still a pre-release out of Mercurial, but IMO better
than the previous 3.2 release.

I recommend to use it in the next Hugin Windows installer. Harry has
been using it already for a long time in the OSX bundle.
