Subject: NewtCanvasAWT Focus Traversal: Remove AWT's requestFocus*() overrides
 in favor of FocusPropertyChangeListener requestFocusNEWTChild()

The AWT's requestFocus*() overrides were intended to receive the AWT focus (default) and
clear it afterwards to forward the focus to the NEWT component -> requestFocusNEWTChild().

This can be achieved simply by using our FocusPropertyChangeListener
and invoking requestFocusNEWTChild() when receiving the focus on the NewtCanvasAWT component.
