Added support for XML-writing VTK_POLYHEDRON from a mapped unstructured grid
Added support for writing VTK_POLYHEDRON
cells when the vtkUnstructuredDataWriter
is used with a cell iterator (this happens when a mapped unstructured grid is used).
Added a test for this where an unstructured grid is directly written and written as proxy for a mapped unstructured grid. For all data modes (appended, binary and ascii) the files written should be binary-same.
