Adding a patch to support revisions for entity_print debug.

@benjy,

I don't like revision_id being latest, does this get the currently published revision or the forward most revision? I think i'd prefer for that to be a separate route.

@benjy, I have changed $revision_id to $revision, since we are reusing the same controller method, I thought it'd be simpler to keep them together. Please confirm if we still need to add new route for 'latest' revision.
