[vtkusers] VTK tutorial, step 5 (Cone5), OSX-Cocoa: fails to capture keyboard events

[Michael Jackson]

It has been a long time since I monkeyed around with all of that but I  
agree with Sean on this one. If we make the examples proper bundles  
then that should fix those issues.
    Thinking more about this it probably does make sense for the fix  
to be put into the Carbon/Cocoa Render window interactor. I guess we  
will just have to test the heck out of the fix.
