Be sure to include jruby jars in classpath so that compilation still works with Jbundler
Allow the config.java_libs to still serve a purpose by not clearing and removing the jars with the same name as others in the list. Also, move the jruby jars to the Traits module to be accessible by both the jar and jbundler trait.
