vtkRibbonFilter can cause subsequent filters to crash

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

This problem was reported by Christopher Bruns in [vtkusers], along with a C++ program to reproduce the crash: http://public.kitware.com/pipermail/vtkusers/2006-June/085755.html

There is a typo in vtkRibbonFilter.cxx, which leads to some bad results copying point and cell data. The following patch seems to correct this:
