Bundled app launcher changes

It's great to see there is a new ant task to create app bundles. But I'm a little bit confus: What is currently the right way to create a java app bundled with a privat jre of OpenJDK7? Is it the new ant task (where can I download it?) or is it the JavaAppLauncher code from Mike/Apple?

>> I'm wondering where this should be checked in, though. Building an application bundle from JARs, resources, and launcher stub is really a deployment task as opposed to a pure JDK feature, but Web Start and the plugin are not open sourced so I don't see a public 'deploy' project happening in the near future. We definitely want to push this out so people can start building applications with the Mac JDK. Anyone have an opinion on that?

Kumar Srinivasan checked in a refactoring of the command-line tools so that all of the runloop management, argument parsing, and other setup is now done in JLI_Launch. That means we can rip out the code that duplicates that work in the app launcher and call through to JLI_Launch instead. I started on this and handed it off to Greg. We should have something to share in the next week or so.
