Overview
Allow instance admins to configure an instance to be more about the collective Reader than the individual blogs. That is, make it so the concept of individual user blogs is downplayed, and the idea of a single "blog" via the Reader view emerges, instead.
Background
WriteFreely is being used more as a place to gather writing from many different people, rather than to give people their own individual blog. We should facilitate that with a different blog UI that looks more like the rest of an instance.

Admins
Implementation
Create a new collection template that uses the same backend user pages header, instead of the centered header on the current collection template. Apply this to: collection, collection-tags, collection-post.
TODO: figure out how to keep the author's name / link somewhere on these pages.
