KRE info page

- The KRE Info page (see screenshot below)
- The resource generator places the generated file in a different folder now. That's why you'll see a big change there.

@davidfowl, @Eilon please review
For the sake of the sample you could conceivable leave the default, but also have another middleware registered *after* the Runtime Info middleware that did something like:

```c#
app.Run(async context => {
    context.Response.StatusCode = 302;
    context.Response.Headers["Location"] = "/runtimeinfo";
});
```

I'm sure I got the codes completely wrong, but the idea would be to redirect all fall-through requests to the proper URL.
