To get a version of mdtool that works without any Xamarin.Mac
licenses.
Also bump maccore to run the mmp regression tests now that
we have a working Xamarin Studio.

[tests] There is now a released version of Xamarin Studio whose mdtool doesn't care about the XM license, so we can run the mmp regression tests again.
It's based on our work, with a few extra commits. That should reduce a
bit the checkout time and ensure more consistent results.
Also bump Touch.Unit since that requires a small API change.
