Compile Razor templates

Requires a working .NET runtime. You can use Mono on Mac and Windows.

npm install -g razor-cli

It works on the convention that you have a directory containing pairs of files on the form _component.cshtml and _component.example.json. Running razor-cli --partials Views/partials --output build/partials will then output a single html file (such as _component.html) per pair.

In its current form, this is little more than a proof of concept. We have a wrapper around a utility using .NET libraries, which is the the piece actually doing the work.

The basic functionality is in place, but we need better error handling. Most substantial improvements will be probably end up in the .NET utility.
