Element list logging facility resurrected as an ElementListObserver (see LoggingElementListObserver).
DebugHelper registers that logging facility. Add a call to your own test apps to log element lists.
Added an additional check implementation for the layout engine checker which allows checking of Knuth element lists using the ElementListObserver. (Usage example: See keep-together2.xml)
