Ported to VS 2015

Hi,

I have ported Usus.NET to VS 2015 and replaced some libs with NuGet packages.

Best regards,

Maxim

Hi Maxim.

Thanks, that is very cool! I reviewed it and found two things I would like you to have a look at before I merge it.

1. Usus.net.Core still references GraphSharp in lib which should also be the nuget package. And there is another invalid reference, I think in Usus.net.Shell.
2. A few of the integration tests fail. For example verification of CyclomaticComplexity. I suspect that is because the compiler generates different IL now. Please have a look at those tests and see if they fail for a valid reason or not.

Thanks again :)
