Shouldn't there be also something like "NOTANSWERED", if user hasn't yet
decided whether to accept registering or not.


Though, I wonder if there is some privacy issue related to
isRegistered/registeredState(). Or there is - web app can
know whether it is being used as the default protocol handler
for some protocol, say mailto: with GMail.
But is the privacy issue bad enough to worry about?

Safer option would be if registeredState() would just return
"ASKED" or "NOTASKED"
