The Albums / Tracks / Artists tabs get a QbzSelect filter (No filter /
Main artist / Performer / Composer / Label / Release name). Changing it
re-queries that category from offset 0 with the search_type and replaces
the list; load-more carries the active filter forward. The filter
resets on every new search. search_type_for_filter is unit-tested.
