Resolves #73.

@boustedo thanks heaps for the contribution! I'll try to do some tests myself (though I have access only to Linux atm), and will get back to you.

@gusztavvargadr I just run .\ci.ps1 restore w10e-virtualbox-core of my PR change under Windows and I got this error:

An error occurred when executing task 'packer-restore'. Error: System.AggregateException: One or more errors occurred. ---> System.MissingMethodException: Method not found: 'Newtonsoft.Json.Linq.JObject Cake.Json.JsonAliases.ParseJsonFromFile(Cake.Core.ICakeContext, Cake.Core.IO.FilePath)'.

I am trying to debug it but I am lost a little bit since I was unable to debug under VS Code yet.

The error is trigger from this line https://github.com/boustedo/packer-templates/blob/master/src/core/cake/template.cake#L214

It work well under MacOSX and Linux using: ./ci.sh --target restore --configuration w10e-virtualbox-core.

I do not understand why it work on other platform but not on Windows. Maybe it's my Windows environment that is the source of the error. But I doubt it. I will continue to debug that. If you have any hint on it, please share and we will find a way to make it work on all platform.

@boustedo thanks for the great analysis, sorry that I did not have the time yet to test it properly.

I can recall I had to fix the versions when 0.22.0 was released at 81536dd#diff-d1b4d7717b81225f983e4c6df57971ea as the dependencies got broken.

I would try the later versions of https://www.nuget.org/packages/Newtonsoft.Json/, maybe it's just an incorrect minimal version specification in Cake.Json. Btw, if we're not directly referencing Newtonsoft.Json, I would not add it as an explicit addin, as that's the responsibility of Cake.Json.

@gusztavvargadr
I make it work by running the Cake.CoreCLR dll with dotnet instead of using the Cake.exe binary. I also have to skip the verification. I don't understand why it work using "dotnet Cake.dll [...]". I will not investigate more for the moment. If you need me to test other stuff, let me know.

@boustedo sorry that I never got to properly test and so merge this. I'm planning to move to the .NET Core tool model soon, so I'm closing this now.
