Title: Add code filepath to code blocks

This is something I've needed forever when writing books and training
material with code samples: the ability to easily list wherea file
should go on the reader's machine:

e.g.

input
``
```app/models/person.rb
class Person
end
```
``

output
```

app/models/person.rb

...

```

Barring putting it into the parser directly, being able to override the
kramed callbacks before render would be nice (probably better).
