[WIP] Windows Support

[smarr]

Here a first experiment to see whether we can get things to run on Windows.

Results: https://ci.appveyor.com/project/smarr/somns/build/build%208%20dev

It's a little hard without having a windows machine. It doesn't go far. For some reason my Ant-foo isn't good enough to get MX to work. So, I am giving up for now. If you need Windows support, please check the changes and try to pick it up from here.

Some more digging, looks like an issue with MX:
