Compatibility to 6.2

These changes should make uncache work with TYPO3 6.2. It's not tested thoroughly yet but works fine so far, although all that Reflection-stuff feels a little hackish…
By using a TransientMemoryBackend when applicable, uncache now works well with EXT:fluidcontent as this one is transferring its configuration (pageTS) through the caching-system.

Hope this helps.

Cheers,
