Property grid navigation improvements.

* Do not handle tab key event when committing property changes so the
  property grid tab navigation works correctly.
* Do not call commit property changes on tab key when no changes are
  pending.
* Skip event handling in the base object value change and changing event
  handlers in case they do not get overloaded in derived objects.
* Do not force focus to canvas on property change so arrow and tab key
  grid navigation work properly.  Forcing the user to click the property
  grid control to edit a single property doesn't make sense.
* Pass properties panel show event up the event stack.
* Do not set focus to canvas in tool dispatcher if it already has the
  focus.
