Direct link to recipe could offer user to login

[josephguillaume]

If I paste a link to a recipe directly in a browser where I am not logged in, I get 404: Not Found with a link to go home.

Instead of going home, logging in, and trying again, it would be useful to be offered to login directly on that page.

This assumes the link is indeed valid - if the user has actually pasted a link from someone else's pod instead of using the viewer, then this wouldn't work. Given that the url does not encode any information about the pod, logging in is probably the only way to tell anyway.
