No robots.txt

It would be good to provide a /robots.txt for (search engine) crawlers. Currently https://bin.bloerg.net/robots.txt returns a 404.

At least /burn/:id URLs should be blocked, I think.

Makes sense but I have no idea if this is actually a breaking change for some installations (i.e. someone set up a specific rule in NGINX for that URL). But I guess the proxy itself would handle that route before it proxies to the application.
