Added test to validate bug report #32
Fixed bug: Fix node factory after loading WikiConfigImpl from file
changed non ascii characters to unicode escapes, exchanged expected and actual in WikiConfigTest, more line ending fixups,
XML serialization code needs the implementing class as the second generics not the interface, fixed the errors reported by the XML serialization test so enable it.
Provide an xml.transform.source interface for users which want to do XML processing of the WikiConfig.
Split up DefaultConfigEn so others can use it as a superclass for their DefaultConfig
DefaultConfig requires WikiConfigImpl to check default and template namespaces. They might be null.
Merge branch '2.0.0-alpha-1' into 2.0.0-simar
