Robin Ward b9abd7dc9e FEATURE: Shared Drafts
This feature can be enabled by choosing a destination for the
`shared drafts category` site setting.

* Staff members can create shared drafts, choosing a destination
category for the topic when it is published.

* Shared Drafts can be viewed in their category, or above the
topic list for the destination category where it will end up.

* When the shared draft is ready, it can be published to the
appropriate category by clicking a button on the topic view.

* When published, Drafts change their timestamps to the current
time, and any edits to the original post are removed.

Sam 29fac1ac18 PERF: improve performance of unread queries
Figuring out what unread topics a user has is a very expensive
operation over time.

Users can easily accumulate 10s of thousands of tracking state rows
(1 for every topic they ever visit)

When figuring out what a user has that is unread we need to join
the tracking state records to the topic table. This can very quickly
lead to cases where you need to scan through the entire topic table.

This commit optimises it so we always keep track of the "first" date
a user has unread topics. Then we can easily filter out all earlier
topics from the join.

We use pg functions, instead of nested queries here to assist the
planner.
