[TYPO3-core] RFC #16396: Implement a Grid View + wizard to enable the backend layout to be adapted to the frontend look and feel

[Steffen Kamper]

Hi,

+1 by reading and testing. Thanks to the complete team for realizing this!
There is some CGL cleaning needed which will be done later in cleanups.
Also sprite generation will be done later as there might be some more 
additions until FF.

Committed to trunk rev 9393
