Make wyam generate RazorPages

[sparkeh9]

So here's a cool use-case for wyam - generate RazorPages (cshtml) instead of plain html.

I am generating blog posts from markdown, I wondered if it would be possible for wyam to generate the output as RazorPages instead of plain HTML, these would then be available for rendering on an ASP.NET MVC backend. These cshtml files would be akin to xamarin android designer or winforms auto-generated UI code, and would be overwritten every time the source changes
