this adds another 'filter' type cache, similar to the visibility and mute caches, to cache the results of status filtering checks. for the moment this keeps all the check calls themselves within the frontend typeconversion code, but i may move this out of the typeconverter in a future PR (also removing the ErrHideStatus means of propagating a hidden status). also tweaks some of the cache invalidation hooks to not make unnecessary calls.
