Subject: Moved the caching stores from ActionController::Caching::Fragments::*
 to ActiveSupport::Cache::*. If you're explicitly referring to a store, like
 ActionController::Caching::Fragments::MemoryStore, you need to update that
 reference with ActiveSupport::Cache::MemoryStore [DHH] Deprecated
 ActionController::Base.fragment_cache_store for
 ActionController::Base.cache_store [DHH] All fragment cache keys are now by
 default prefixed with the 'views/' namespace [DHH] Added
 ActiveRecord::Base.cache_key to make it easier to cache Active Records in
 combination with the new ActiveSupport::Cache::* libraries [DHH] Added
 ActiveSupport::Gzip.decompress/compress(source) as an easy wrapper for Zlib
 [Tobias Luetke] Included MemCache-Client to make the improved
 ActiveSupport::Cache::MemCacheStore work out of the box [Bob Cottrell, Eric
 Hodel] Added config.cache_store to environment options to control the default
 cache store (default is FileStore if tmp/cache is present, otherwise
 MemoryStore is used) [DHH]
