[vtkusers] TDx interactor and focus

[Matt Spong]

For the benefit of future Googlers, the solution to this problem was
to override QVTKWidget::focusOutEvent and ::focusInEvent, and call:

GetInteractor()->StartListening()

...and...

GetInteractor()->StopListening()

... respectively, in addition to QVTKWidget's implementations.
