Binary XML 0.2 Released

Added better debugging support in the compiled XML classes by tracking the line numbers in the original XML document. That way if for some strange reason the compiled class threw a SAXException you would see where it originated from in the original document.

Also added some initial support for CallBacks. All the interfaces were modified, and expect them to be modified one more time. For the time being, we are using Processing Instructions for the callbacks. They work, but the target value section can be improved to provide properties for the callback.

Now 100% of all the interfaces are implemented with some base versions, and you can start to get a feel for how to play with them.
