Changes: * Drop Users.id_to_name. * Don't cache Users.name_to_id. * Replace calls to name_to_id with find_by_name when possible. * Don't autodefine creator_name in belongs_to_creator. * Don't autodefine updater_name in belongs_to_updater. * Instead manually define creator_name / updater_name only on models that need to return these fields in the api. id_to_name was cached to reduce the impact of N+1 query patterns in certain places, especially in api responses that return creator_name / updater_name fields. But it still meant we were doing N calls to memcache. Using `includes` to prefetch users avoids this N+1 pattern. name_to_id had no need be cached, it was never used in any performance- sensitive contexts. Avoiding caching also avoids the need to keep these caches consistent.
