* Migrated the caches to return `NSSet` to eliminate duplicate objects when your cache keys overlap * Introduced new recursive strategy for building cache keys in `RKInMemoryManagedObjectCache` * Added support for array cache key values in `RKFetchRequestManagedObjectCache` * Re-enabled a slew of tests that were disabled during 0.20 development
