Shifted NavigationManager caching to use node instances rather than node pks. Improved (i.e. added) a distinction between having a cache for a node and having a Navigation instance somewhere in the cache. Refactored Navigation.is_active for better clarity. Added cache clearing for previously-uncached, directly-hosted navigation. Adjusted recursenavigation to accept either a node or a queryset/iterable. Added targeting_navigation filter.
