0.3.3

This release adds an interface similar to a file browser when you have a directory selected. It provides a simple way to navigate a project, as well as a way to rename or delete files in bulk. The release also displays the icon for the JAR version when run from the command line, thanks to a PR from Github user kumarshantanu. Lastly, all the templates have been updated to use Clojure 1.6, and the Clojure game template is now using play-clj 0.3.0, which I released last night.
