Clojurians Log v2

@tcrawley oops, I was thinking else than writing, so these break: - all custom response handling extensions break (as the multimethod doesn't exist anymore, fails most likely at compile time, which is good) - some middleware might break as the request doesn't auto-deref Delays as before. It was an implementation detail, so I guess it's ok.

I could also add support to async-ring, via an option like :async? (same as Jetty has).

Also, tempted to autoformat code for default indentation, but it's your codebase, so only if you think it's ok.

Whats changed from 1.1.4 to 2.x in terms of wrap-params? Im seeing it work in some cases where it did before, and in other cases it breaks and I have to slurp the body.
