Search Pagination

[Nutomic]

Was removed in #6397. Also sort, liked_only and disliked_only params were removed from search.

Its really not possible to do this with the all type, because cursors are only going to work on individual tables.

Cursor pagination, with all these other specific filters already do work for the single-type list fetches.

[Nutomic]

Its not so difficult, we only need to merge the cursors for each query type into a single string (eg comma separated list of cursors).

We could also use the cursors for "more results" buttons, that point to second page of the individual type.
