[newsmake] add a visual studio project system.

[AraHaan]

Issue Description

I just would like a plain flat out Visual Studio project system for this project. And maybe somehow add support for dotnet new on this type of project too.

List of things to be in the project system:

• Custom project nodes.
• Project file type is *.newsmakeproj?
• Project system that can only build, not debug as the generated output is not debugable (becomes generated as plain text / markdown).

Probably best to have the new Sdk style system that I made handle generation of the changelog stuff when building that way it uses a build task that then generates the stuff.

Another issue: making the tool update any project file when they go to make another release however.
