We definitely want to return the cursor in `UnifiedPaginator._get_cursor()`.
All the calculation things should be on the paginator, not on the page, right?
Adjusting the paginator tag.
Return the total known count of objects, not the end_index of a page.
Using the same function for multiple things… I hope that works, otherwise we should split the generic bit off.
Removing the `set_page_name` tag, this should surely be done in the views, right?
