MSBuild final !

```
[23:30:18] <moonpyk> meebey: untested pull req, I just want to know if travis builds ok
[23:30:59] <moonpyk> this messes up a bit the sln file, but in fact, this is needed
[23:31:16] <moonpyk> with that smuxi build and runs with np on win
```

Good to merge IMHO if travis build passes and nothing broken on *NIX.
