Is this something that will change with different versions of the app? Should it
just be fetched out of band with the extension itself?

Hmm. That's a good point. I was also thinking of syncing icon URLs and creating
a WebContents to fetch the icons on down-sync. I suppose I could fetch the whole
page and then get the icons and descriptions out of that.

I've sent an email to meacer@ asking if there would be security concerns there.
