Enable users to move to prev/next page without having to scroll all the
way to the bottom of the page.
Furthermore, ensure consistency with entry.html which has top and bottom
pagination.
Why:
It is nice to have the ability to mark an entire category as read in the
UI. The API already exposes that functionality anyway, so for
consistency reasons, expose it in the UI as well
What:
Add a new handler in the UI to markCategoryAsRead() and amend views and
router to expose the functionality in the UI
