Update Samples for 10.2

[timwindsor]

Samples need to be updated to add a listener for 'webworksready' after the load event is received, to ensure they work properly on later 10.1 and 10.2 OS builds. The following samples add a listener for 'webworksready' without guaranteeing the document has loaded. The result is typically a white screen.
