TODO in reports.c crossed off. Adding query parameters to the pagination
links so that data is consistent across pages with no user interaction
on the links.

(Previously the 'since' parameter would not populate through to the
next/prev URLs. So if one blindly followed the next/prev links after
specifying the since parameters, you wouldn't receive data from those
next pages unless you manually put the since parameter onto the returned
next/prev page links.)
