- beginning to respect fixed values from xsd

- fixing bug with default values for select widgets
- some more unit tests for repeating items, and xsd attributes
- parsing xsd when creating the form and presenting a combobox with element names that are possible root tag names
- ensuring that there can't be multiple output methods that output the same extension
- moving createxmlcontenttype to createformwizard in wcm where it belongs.
