[vtkusers] [Java] Removing default shortcut

[Sebastien Jourdain]

If you don't have any issue with (r, u, w, s), you should handle your
keypress event at the Java level. You can not subclass a C++ class in Java
and hope to use it.
If you can not unregistered key press event on the C++ InteractorStyle with
API call then you are in trouble with what you are trying to achieve unless
you picked the wrong interactor style.

HTH,

Seb
