Easy way to link to the full val page from within the result of an http val

[boucher]

It's not exactly hard to add a link back to your val, but it might be nice to have a one line / one flag way to inject a "Fork this" or "Edit this on val.town" kind of banner/link on to a page being served from an http val.

Agreed! One of my favorite lines of Townie's prompt:

Tastefully add a view source link back to the user's val
if there's a natural spot for it and it fits in the context 
of what they're building. You can generate the val source
 url via `import.meta.url.replace("esm.town", "val.town")`.

A pattern I quite like is using a script in your head to share generic bits of logic (ex: Ex: https://www.val.town/v/pomdtr/dotShortcut)

We could adapt https://www.val.town/v/andreterron/codeOnValTown to work this way.
