- Extend shitlist time from 4-8m to 40-60m
      - Add some shitlist logging
      - Don't shitlist twice when unreachable on all transports
      - Exclude netDb-listed unreachable peers from inbound tunnels;
        this won't help much since there are very few of these now
      - Remove 10s delay on inbound UDP connections used for the
        0.6.1.10 transition
      - Track and display UDP connection direction on peers.jsp
      - Show shitlist status in-line on profiles.jsp
