[TYPO3-mvc] Property Mapper merged

[Sebastian Kurfürst]

Hey everybody,

just wanted to let you know: I merged the new property mapper to Master,
and also the related MVC changes. This brings Extbase very very much in
sync with FLOW3 again.

All the features are still deactivated by default, in order to use the
new property mapper
insert |config.tx_extbase.features.rewrittenPropertyMapper = 1| into
your TypoScript setup. *This is not yet the final way to enable the new
property mapper, so use it only for testing!*

We will discuss how to enable this feature in a backwards-compatible
manner at T3DD11.

Greets, and let us know of any problems!
Sebastian
