checkpoint of xforms improvements

- mostly functional hgroup implementation
- refactoring to support hgroups, make widgets behave better as inline elements
- figured out a way to get rid of dojo's inflight error watcher
- partial support for totalDigits (blocked by a dojo bug)
- improved support for length schema constraint
- refactoring of create widget code on the way to supporting config based on schema type, xform type, and appearance
- fix for silly bug in select workflow portion of create form wizard
