A jenkins plugin for leiningen builds.

For now this has to be installed manually, the following steps should be taken:

• compile the hpi plugin with: mvn package
• in jenkins, go to "configure jenkins" then advanced and upload the resulting .hpi file to jenkins
• restart jenkins
• in jenkins main configuration, set the full path to the leiningen standalone JAR (as found here: https://github.com/downloads/technomancy/leiningen/leiningen-2.0.0-preview7-standalone.jar)
• jobs can now be created with leiningen build steps

If you want to archive artifacts, you will have to specify the path to the artifacts you want archived in a post build step target/*.jar or target/*.war for lein2 works perfectly
