Rework for stability

This release updates the serialization plugin to be based upon the design described in the serialization keep. This has improved architecture and dependability.

• Naming is now well defined: If present on type or use site the XmlName tag wins. Otherwise for tags the serialization name at the type declaration wins (XML tags should be named the same independent of use). For attributes the use site name wins (attributes are generally primitives and generic type names are not useful)
