Clojurians Log v2

I've added Integrant :doc annotations to all the keywords and added a custom doc macro to the REPL that supports them. What this means is that you can look up the docstring for an Integrant keyword at the Duct REPL. For example, (doc :duct.module/logging) will print the docstring on the logging module.

I've also updated all the dependencies.

My plan is to go into a release candidate within the next month. The only change I anticipate making is to add a :hiccup feature to the web module, so that people can choose whether or not they want that middleware.

If anyone had any feedback, now's a good time to give it.
