fixed bug with checkboxes

partially removed need for sample instance xml - i'm doing a bunch of hacks at the moment to get around it - basically using xmlbeans to generate the sample xml, and then cleaning it up.  ended up not needing to do insane things in javascript with this approach.  emailed joern at chiba to see if he has suggestions for how others deal with this issue.
serializing the template configuration using object serialization for now.  it'll work good for the demo and we'll do something more robust/human readable post demo.  this required a bunch of refactoring and springifying the TemplateService, but we're now reading back xsds and xsls from the repository which is sorta a nice thing i think.
remove the preview form wizard step from create xml content type flow.
tried getting rid of a temporary file in generating the xform but failed.  need to find a way to get an url to a noderef that the xform can use to reference the xsd.  emailed london people about that.  but still did some refactoring along those lines.
