[flexcoders] Is an event dispatched when an AIR app is closing?

[Daniel Gold]

I'm working on an online/offline AIR app and was wondering if there was any
way to detect that an AIR app is closing so I can cache my data models? If
the user closes the app while online and then opens it later offline, I'd
like them to have access to the last data set. I could achieve this by
constantly mirroring the remote data but was hoping to avoid that since the
majority of the time the users will be online and it won't be necessary.
