#152: Support list_metadata_by_type in Wiki::Toolkit -------------------------+-------------------------------------------------- Reporter: nick | Owner: nick Type: enhancement | Status: new Priority: normal | Milestone: Component: openguides | Version: svn Severity: normal | Keywords: wikitoolkit -------------------------+-------------------------------------------------- So we can do dropdowns / offer completions on categories, locales etc, we need a list_metadata_by_type method

This needs to only return metadata associated with the latest moderated version of the nodes, so as to avoid old and spam metadata.

Probably one for the hack weekend.
