First commit of new pagetype-configrepository

The next release will remove all controller-centric code out of cmsable.
Configurations of pages will no longer rely on any controller or class.
It will be bounded to the pagetype.
So no more class-bounded db-entries and all controller depending code
will be deleted.
The only remaining controller-related part will be ControllerCreator,
which will boot/create your controller like before.
But this does not mean that you have to do something with your
controller. Configure the dependencies of your controller.
