Now that Site Name and Last Access are no longer in the unl_sites db table the sort for them was broken.
Use a custom sort function for all the columns.

No real reason to weigh cron down with updating site name and last access timestamp constantly.
The update db queries for those two fields can just be run when the site list is accessed.

Replace the run-at-request complicated JOIN db query with a cron task that fills in name and access in two new unl_sites db fields.
