Use litepager for BW views

To add a bit more data, I initially saw an issue on the /user page, in the "Following" block. It performs this query, which won't scale well as the user table grows:

SELECT COUNT(*) AS expression FROM (
SELECT 1 AS expression
FROM users users
INNER JOIN flag_content flag_content_users ON users.uid = flag_content_users.content_id AND flag_content_users.fid = '8'
WHERE (( (flag_content_users.uid = '9' ) )AND(( (users.status <> '0') )))
) subquery

Let's just avoid the subquery altogether and not have a typical pager there.
