Widget structure questions

Great, thanks Mark, that's very useful.  Like you, I'm parsing the
manifest.xml files myself right now but will check into the
revIDEExtensionProperty and revIDEExtensionsFetchMetadata() handlers.

I'm getting the path to the user extensions folder the same way as
you.  Strange that they'd advise you not to use the official way to get
those paths, especially the system extensions since it will be different on
each platform.
