Allow colon in formulas, as in ovemer:3, by analogy with search.
Fix 'show:' column headers.
Refactor.
Paper list query internals.
Update minimum schema version.
Nit
PaperSearch stores a paper list.

This is much cleaner than a temporary table.
Paper list query: Move paperId constraint into subtables.
Internal: Obtain scores the same place you obtain submitted review count.
Formulas: Allow aggregates like any(pref>0 and ovemer=2).

That means "some user had pref>0 and set ovemer=2."
Don't show preferences to other users.
What the hell, parse ≤≥≠ in formulas
Support "formula:" formula search.
Quiet warning.
