TYPO3 Core

Currently the cacheFactory handles configuration details like searching for cache frontend fallbacks and such. But this is not scope of the factory, it should just take care of creating caches according to configuration given by the cacheManager.

The patch moves the configuration handling to the cacheManager and remove the globals registration of cacheFrontends and cacheBackends because they are obsolete with a working autoload configuration.

This is also much better in sync with FLOW3 implementation this way.

Patch is covered by unit tests as usual ...
