[vtkusers] Blocking 'Q' and 'E' keys

[Shakes]

Hi Alan,

Not sure if this will do what u need. But when I needed to unbind the 
mouse click events I used

///Unbind the right mouse button events as Qt uses context menu. 
QVTKWidget::GetRenderWindow()->GetInteractor()->RemoveObservers(vtkCommand::RightButtonPressEvent); 

QVTKWidget::GetRenderWindow()->GetInteractor()->RemoveObservers(vtkCommand::RightButtonReleaseEvent);

Not sure how to unbind keys, perhaps change the 
vtkCommand::RightButtonPressEvent bits?

Hope that helps
Cheers
Shakes
