Update the notebook before running the sample in case it is a modal

dialog, (but the best thing to do is to just always make a panel with
buttons to launch the dialog...)

Fix the find text to ensure that the found text is visible

Added ability to open a PyShell window that has the app and demo frame
preloaded in the namespace.

+Added a menu item in the demo that will open a PyShell window that has
+the app and demo frame preloaded in the namespace.  This is another
+good way to explore and play with the objects in the currently running
+sample.  For example, load the Button sample and then do the following
+in the PyShell::
+
+	>>> b = frame.demoPage.GetChildren()[0]
+	>>> for x in range(0, 500, 10):
+	...     b.Move((x, 50))
+	...     app.Yield(True)
