Bundled app launcher changes

> There should be a way to add a number of jars to the classpath, which will implicitly get copied into (bundle)/Contents/Java. Is that just by adding more <jarfile/> tags? Should there be an affordance for specifying non-jar/non-classpath resources that should also get copied into (bundle)/Contents/Java? It may make sense to provide a <resource/> tag for art or other Mac-specific resources to be copied into (bundle).app/Contents/Resources. Or perhaps just a <copy/> tag that takes a source and a destination.
