[IDC-1994] Sort series list by SeriesNumber, and sort by same SeriesNumber by date/time. (#2010)

* Sort based on SeriesNumber and SeriesDate/SeriesTime.

* Harden, and perform final sort in algorithm if last N entries have the same SeriesNumber.

* Switch to insertion rather than sorting as sorting is too slow. Reimplement low priority sorting into new insertion method.

* Fix local file viewing.
