This commit turns all dial logs into log.Events.

Everything's great except for one problem:
The LoggableMap I'm using does not print out things
correctly. I gave it peer.IDs, and Multiaddrs
and both got logged as nothing `{}` (didn't even call
their String() methods!) So, for now, this function
encodes it when called... This is wrong and should be
fixed before being merged in. Otherwise we  will be
constantly encoding peer.IDs and Multiaddrs without
needing to.

@briantigerchow how do you suggest doing this?
I don't know my way around your Loggable.
