Apply fix for bug 997.

Browse Source 
Hidden service clients didn't use a cached service descriptor that
was older than 15 minutes, but wouldn't fetch a new one either. Now,
use a cached descriptor no matter how old it is and only fetch a new
one when all introduction points fail. Fix for bug 997. Patch from
Marcus Griep.
