Title: Expose KFDataCollectionViewDataSourceController class

The class was never used internally nor was it being exposed for others to implement.

@kylef it was either this or make ```KFDataCollectionViewController``` return it as the default data source class. Since this is a bit of a hack and only really provided for legacy transition I thought it best to rather expose the class than force it's use.
