Also move the dependent classes: vtkImageLabelOutline, vtkImageNeighborhoodFilter,
vtkImageResliceMask, vtkImageSlice to MRMLLogic

Ultimately, these class should be added to the slicer/VTK git fork and eventually
ported to the offical VTK repository.

All Cxx classes and Tcl script referencing vtkSlicerSliceLogic and vtkSlicerSliceLayerLogic
have also been updated.

Tcl wrapping hints have been moved from Base/Logic/Wrapping/Tcl/hints to
Libs/MRMLLogic/Wrapping/Tcl/hints
