Title: Redaction

These patches add support for "redactions" to the API, which allow the hiding of historical versions of an object and will be used during the license change process and potentially in any later DWG actions.

The redactions API consists of a set of new API calls for nodes, ways and relations to hide historical versions. Redactions themselves are a new resource, with creation and management via the web interface. The web interface & API have also been modified to hide redacted versions via the browse pages, changeset downloads, and other avenues of displaying historical information.
