Windows binary saga

[Dirk Hohndel]

And after a lot more of what I would mostly call "random changes that
make no sense" I appear to have a working daily build.

Please try subsurface-4.4.97-41-g148b30849aba.exe (or a newer version, in
case you read this after I make a newer one available).

I'm especially interested in

a) does it work on Windows 10
b) does it work with Subsurface cloud storage
c) general testing :-)

Thanks
