Allow the input tree or table to this item to be set to NULL.

This will be useful when we remove the input data in Visomics after
this item has been instantiated.

Put all wrap hierarchy files in VTK_MODULES_DIR

This allows for much simpler code when wrapping an external VTK module.
Also just check if the module is wrap hierarchy excluded - the
<module>_BINARY_DIR will not exist when building against VTK.

Add vtkPainterDeviceAdapter::SendMaterialProperties()

This adds a new virtual method to vtkPainterDeviceAdapter named
SendMaterialProperties() which instructs the graphics framework
to set up material properties (ambient, diffuse, specular color
and specular power).

This virtual method is implemented by the vtkOpenGLPainterDeviceAdapter
makes the appropriate glMaterialf() calls to set up the material.

This is needed for the per-block coloring support in the new
multi-block rendering code.

Check if the PythonD target exists

This allows for external Python wrapping to work, and also continues to
work as expected when wrapping VTK modules. The dependency source
directory was also being added twice (once here, and once with the
binary directory in CMake/Wrapping.cmake).
