Create empty robots.txt. Closes #3635

#3635

This creates /homepage/robots.txt, but clients will look for exactly /robots.txt

Looking at server.js we don't have any static file handler for the root. I think the easiest way to handle this will be to add another endpoint to server.js (i.e., app.get("/robots.txt", ...)) that serves up something empty.

I added it now to the server.js

Not sure if I've done it right. Please correct me if its wrong.

Looks good, thanks!
