Fix major bug in announcements: mfOpennetNoderefRejected had a timeout of 10 seconds, the rest were 4 minutes. Consequently we only wait 10 seconds. This explains why we only see replies (either noderefs or not-wanted notices) from a handful of nodes, even though not-near-seed opennet nodes seem to see announcements very rarely.
Detect this error!
Reduce the announce timeout, 4 minutes is too long.
Fix NPE in announcement. Fortunately we have already done what we need to do here...
Build 1431, mandatory February 2nd.
