Clojure 1.4 By Default

Neocons now depends on org.clojure/clojure version 1.4.0. It is still compatible with Clojure 1.3 and if your project.clj depends on 1.3, it will be used, but 1.4 is the default now.

We encourage all users to upgrade to 1.4, it is a drop-in replacement for the majority of projects out there.
