Howdy - first, thanks for such a great framework - it has saved a lot of
development effort.

My question is straightforward, what delegate is called by the updater
if the appcast isn't found or the URL where it is located at times out?
I have a case where I normally want to force users to upgrade (the app
is a client communicating with a server that need to align their schema
versions) but if I can't connect to the server (and get the appcast.xml)
the app runs in "disconnected" mode and no upgrade is required. Is
there a callback(delegate) that tells me that Sparkle looked for but
didn't find the appcast at all (like didNotFinishLoadingAppcast or
didNotFindAppcast)?

Thanks!
