- Initialize structs with field names
- A bit of unreachable code (defers)

This commit actually removes the previously introduced
chan net.NetMessage, in favor of raw []byte. It plays
nicer with crypto/spipe, and it makes more sense in the
context of a "single connection", i.e. I already know the
peer I'm talking to, from the connection. The NetMessage
additional Peer is useful swarm and up.

This Commit changes the relationship between Conn and Swarm.
After this, Conn is significantly more autonomous, and follows
an interface.

From here, it will be very easy to make the MultiConn (that
handles multiple Conns per peer).

transition our use of the net package to multiaddr/net

and other logging switches. I kept the u.PErr and u.POut in cli
commands, as those do need to write raw output directly.

dependencies are vendored into Godeps/_workspace and commit versions are
recorded in Godeps.json
