* ensure that errors checking status visibility / converting aren't dropped * add some more context to error messages * include calling function name in log entries * don't error on timelining hidden status * further code to ignore statusfilter.ErrHideStatus type errors * remove unused error type * add local instance status / domain / user counts * add checks for localhost * rename from InstanceCounts to LocalInstance * improved code comment
