NOTE: This method is called only if you
implemented IwodAppUpdateNotify
interface in your application, and wodAppUp.Notification
property has received reference to instance of your
implementation.
This notification method is called when you
should close your application so that wodAppUpdate can
perform file replacement. You should use this notification
to store any settings, to close file handles etc..
wodAppUpdate will post WM_CLOSE message to your
application anyway, which will most probably cause it to be
closed, but it is advised that you close your application
by yourself - usually you know better how to do it
nicely.
