Add better server and client logging (for development)

[GentlemanHal]

Currently the server doesn't really log anything so it's difficult to know what's going on.

For example issue #30 happened while the server was running in 'monitor mode' but I didn't know if it was happening intermittently on some calls or on every call and my internet was just being slow (which may have been part of the cause).

We should have an access log for every endpoint at least.

What is the best way to log? Just using clojure tools logging?

Sysout as the appender, following the 12 factor app principles: http://12factor.net/logs

Unsure about the library side of things. Perhaps we don't need one? No problem including one, perhaps there is one in our inheritance tree already
