* Add a "Newest" tab to the Forums landing page to order ALL forum posts
(comments) by most recent, paginated.
* Add a "Views" cooldown in Redis: viewing the same post multiple times
within 1 hour doesn't ++ the view count with every page load, per user
per thread ID.
* Update the paginators to handle unlimited numbers of pages: shows max
7 page buttons with your current page towards the middle.
* General ability to jump to the "last page" of anything: use a negative
page size like ?page=-1 and it acts like the last page.
