v2.11.0 — audit feed filters (A81)

A81: the audit log is now filterable. The Audit page already recorded every privileged action (web actions and the result of every broker call) with the acting user, IP, outcome and redacted arguments — now you can filter it by action, result (succeeded/failed), user, and date range. Filters are reflected in the URL so a filtered view can be shared or bookmarked.
