* Don't let the TCP transport alone shitlist a peer, since other
transports may be working. Also display whether TCP connections are
inbound or outbound on the peers page.
* Fixed some substantial bugs in the SSU introducers where we wouldn't
talk to anyone who didn't expose an IP (even if they had introducers),
among other goofy things.
* When dealing with SSU introducers, send them all a packet at 3s/6s/9s,
rather than sending one a packet at 3s, then another a packet at 6s,
and a third a packet at 9s.
* Fixed Syndie attachments (oops)
