NEWT/Android: Fix BACK button implementation, use different KeyCode mappings and allowing native action to be suppressed.

- Don't trust soft-kbd visibility state, but perform invisible action. If the latter
  was successful - soft-kbd was visible before.

- Map BACK to VK_KEYBOARD_INVISIBLE and propagate it,
  if soft-kbd was visible before.
  No native default action is performed.

- Map BACK to VK_ESCAPE event and propagate it,
  if soft-kbd was invisible _and_ an activity was registered via registerActivity(Activity),
  i.e. by NewtBaseActivity.
  Otherwise proceed w/ default action (-> activity.finish()).

- If the KeyListener consumed the [EVENT_KEY_RELEASED, VK_ESCAPE] event,
  it will be suppressed and no default action performed.
  This allows applications to have a custom 'ESCAPE' or 'BACK' handling.
  Otherwise (not consumed) the default action is performed.
