Comment links should scroll down to the relevant comment

Links in the format http://local.wordpress.dev/{post}/#comment-{comment-id} don't work, the fragment is clearly confusing Backbone.

Should we register a new route for comments? Something like :post/comment/:comment?

If so, this endpoint should display the :post as normal, and scroll to the comment on load.

It was a routing issue.

However, it would be nice if the page scrolled down to the relevant comment ID.
