Auto apply CakePHP code standards
Significant fixes and removal of functionality and code committed at 4d447b3d783496134fc79c2509e52c4f1a94de9c which attempted to implement Cache grouping, unnecessarily name-spaced the runtime config, inappropriately bound Model caching behaviour to the application layer through HTTP_CACHE_CONTROL and caused the the cache to always use the default configuration - ouch
Tested against cake 2.2 and 2.6, updated Readme
